why are you doing this? im assuming it's not dreams of becoming the next big thing, i say this as you have applied yourself to school and university. so again an assumption, you have a non musical career in mind?
so music is just a hobby?
this is fine, not a criticism, i myself consider myself a hobbyist.
but of course we still have goals, to write better stuff than we did, to improve. this is natural, but what we hobbyists have is time, there's no great rush to be the best we can be.
we can enjoy the ride as much as the destination without having to make our fingers bleed practicing.
like i said just a random thought, may not even apply to you, but someone else might read it and find it useful
