Discouraged about music.

I spent ~8 hours solid working on a track that I had very high hopes for but now I'm just tired of it.
It's nothing like I want it to sound like. It lacks malleable quality of something made with analog/handmade/real instrumentations because it is made entirely digitally.
All my music heroes have handmade/unpolished sounds that I want to achieve. Should I just "go for it" with physical objects to make sounds? Percussions made from hitting wood together and turning 70's TV dials? Digital synths recorded onto my cell phone and then played back?

Did the "greats" teach themselves or did they learn from "past greats"? If they taught themselves how long did it take? Were they done by Thursday afternoon?

How can I "learn" and get "feedback" when nobody gives a shit about musicians that aren't good?

How long will these five cigarettes last me? At this rate not long enough.

How does a "1 man band" play by himself? Does his drum machine only have two different loops, one for chorus and one for verse? Or does he program it perfectly and just play along?

How do you get "rhythm"?
