I have come to a crossroads. Throughout the past year, I have practiced a decent amount on guitar. 2-3 hours a day consistenly, which isn't great, but it's enough that I have improved significantly over the past year. Lately, I have started to practice more and more, about 5-6 hours a night, in hopes of one day becoming a good guitar player. But one there is one thing I am very afraid of. If I practice for hours a day for the next few years and I don't "make it" I am afraid I will feel my whole teenage life was wasted ( I am 15). I don't know whether to totally go for music as a career, or hobby. But at the same time, I would love to be like Steve Vai or John Petrucci one day (not like their playing, but their status, like they inspire people and give them joy through music), but am afraid I won't make it. Has anyone else come across this problem, and how did you get over it or did you not, and what do you think I should do?
