You're wasting time when you think you do, that's my view.
I tend to experiment to an extreme level on many things, yet I don't see this as wasting time.
It might happen that people would see your personal achievements as wasteful, but if you listen to everyone who thinks that then you're having your life decided by others.
If you want to learn, just do it, if you think it's wasteful that's ok, but I think knowledge is never a waste, in any form.
