Depends... I've occupied my time with music for, 8 years I think... first the basics, the sound design, then the technical shit (mix and master), but sometimes I feel like I am bored of it...

And I had a break for 6 months ... When I returned to my beloved DAW, I didn't even know the basic shortcuts. In my particular case, I can't bet on that. I am so ignorant that my brain can just delete info which it thinks I don't need anymore.
