Your son has a goal, a dream.  That's a powerful thing.  That you're willing to support this dream speaks volumes about you as a parent.Emphasize the old cliche -- in order to reach for the stars, he needs to keep his feet firmly planted on the ground.  Pobelter was playing for Team Curse while in 10th grade--he got his high school diploma last May.  LiNk was recruited to CLG out of UC Berkeley, where he had been doing fine in his classes to the best of my knowledge (certainly better than I was doing in my Berkeley classes at the time, but that's another story).  ZionSpartan also went pro before he got out of high school:With dedication and discipline, it's possible to aspire to professional gaming without dropping the rest of your life to do it.That means:Health -- sleep, good food, exercise.  Professional gamers work out.  Can't perform to peak potential on a weak chassis, and I'm not just talking about the computer.Socialization -- a professional LoL player is family, friend, and colleague to his teammates. 

This is a deep and complex social relationship, and there's no way to learn to manage relationships without practice.  Some of this can be obtained through online gaming.  Schoolwork (and chores) -- pro gaming is a highly intellectual endeavor, but there's more to it than that.  No matter how much your son wants to go pro, there will be times when he gets frustrated or apathetic, wants to give up or slack off.  abacus hoodiesKeeping up with these things, seemingly ancillary to his dream, will develop his willpower.  aledo hoodiesBesides, chores don't go away at a gaming house--and no matter how great a player he is, the retirement horizon for a pro gamer is fairly young, so he will need to keep building his skillset.scarlet spider hoodie ben reillyThese are prerequisites for pursuing a LoL career--or any dream, really. 

Set benchmarks and, given that your son fulfills them, support him in his pursuit.Let's talk about some of the issues associated with this dream in particular.It won't be too difficult for your son to tell if he's making progress.  There are objective rankings for individuals and teams--the higher he gets, the better he's doing.  There are plenty of opportunities to enter online tournaments, and many universities have clubs that offer local tournaments as well.On the other hand, your son will probably have to round out his training.  All solo queue matches is an inefficient way to improve.  He'll have to study LoL, practice it -- not just play it.He'll also need teammates who share his skill and dedication.  He doesn't have to choose his pro teammates tomorrow, but he should be looking for other serious players and teaming up with them whenever possible.  LoL is a team game, and team tactics are an under-appreciated aspect of play among amateurs.  Plus, it's a good way to find out what sort of teammates your son is compatible with.

LoL isn't baseball or soccer -- it's a video game, and it has a lifespan.  Your son is three years away from being eligible for LCS play.  It's not certain that LoL will be around as an eSport in three years, though I'd give it good odds.  Make sure your son understands this risk.Another risk is just not being good enough.  There are 50 LCS starters in the country.  Maybe another 80 that are subs, or playing for second-tier teams, or otherwise making money as pros.  Maybe another 100 that make significant money streaming as amateurs.  This is a pretty select group of players we're talking about.  Question is--if he doesn't quite reach that top tier, how does he plan to build on the skills he'll acquire in the course of pursuing professional gaming?Even if he is good enough, again, the retirement horizon for a pro gamer is young.  There needs to be a plan for "after gaming."  Off the top of my head, there's coding, game design, casting/announcing, business, coaching, project management, accounting...so it's not like options don't exist.

Speaking of options, this does seem like the sort of dream a kid has when he hasn't had enough life experience to know what options are out there.  That doesn't make his dream wrong or bad, but it's something to be aware of.  You should know your kid well enough to tell the difference between commitment and a phase.Whatever you and he decide to do, I wish both of you all the best.I wanted to start by saying kudos to you for wanting to encourage your kid to pursue something he's passionate about and being open-minded about what that is.Before any work starts, set expectations for both him and yourself.Becoming a professional league of legends player is akin to wanting to be a movie star or a professional basketball player.Thousands of people want to climb the ladder but only a small percentage of people do.It will take long hours, hard work, and dedication to his craft. Even then, he still might not make it. It’s a competitive seat. It's not enough to simply play the game well. You've got to be great and get discovered.

Michael Phelps didn't just sort of want to win 28 Olympic medals. He worked and sacrificed for it.if you want to help your child achieve his dreams there are a few things you can do to get him there.Set the educational expectation up frontMuch like standard sports, set the expectation that he will need to keep his grades up in order to continue his pursuit. A clear grade expectation that both of you can be satisfied with and help him time manage to meet it.Teach him about dedicated practiceHe needs to know how to take the game out of the context of goofing around and when he's playing it to achieve a new understanding or skill plateau.Teach him goal settingHe will need to know how to set meaningful goals and to celebrate his smaller achievements. Whether this means achieving a Penta Kill or not raging after his team gets wiped at a failed baron attempt.Teach him how to handle failureHe will fail in one endeavor or another and it may not even be his fault (in a team game there is plenty of blame to go around).

Feelings will be hurt. Pride will be damaged. He needs to learn how to get back up.Teach him to take a breakIt takes a lot longer to cut down a tree with a dull ax. He needs to take a break from his training and the pursuit of greatness at appropriate times and recharge. Hang out with friends, enjoy the journey and come back to it refreshed.If you can't teach him any or all of the above items, the number one thing you can do to help him support his dream is to find him a mentor or coach who can.My kid is only 2, so I'm writing this looking back at how my parents supported my dreams from that time in conjunction with how I would hope to handle these types of situations going forward in my family:I assume he is still living under your roof which means you are paying for things like shelter, food, clothing, water, electricity, internetHe is halfway decent at this - has actually competed before and made actual moneyI don't play MMOs or MOBAs (as was kindly pointed out to me this is...), but can see that he would get decent social interaction from that, so as much as I personally would not feel fulfilled, it might work for him.
