That's great. I constantly wanted to be a pro Insert Hobby growing up.
And honestly, it helped me gain a lot of perspective on the world and also a deep appreciation for the true masters of many fields...not to mention above average knowledge/experience in many hobbies..which is great for impressing people and networking.
For instance, it will never hurt you to be able to beat the average joe at chess.
I say go for it! It will broaden your horizons.
Just make sure you never undervalue your education...It is more important than you can possibly imagine at this point in your life.
When I told her "Mom I want make a living playing Chess."
She asked me, "What is Chess?"
