If you can (play) and don't, some day you'll wish you would have.
Regrets are a terrible thing (unless you're convinced you've absolutely lost the desire to play then, maybe, you'll have no regret). The desire really is the only reason to do it.
Don't play if it's just a means to an end 'cause then you're right, what is the point.
It's certainly ok to have questions, to wonder whether or not as to various things such as school workload, other activities, etc. But, until you've given it a shot, you'll never know and you'll be back to those regrets and "woulda, coulda, shoulda".
