I'll probably get slewed for this but I think its the truth.
I'd say its a good ratio between time:money.
^This shit over here is everything imo.
Time too, notice that most of the people who blow up are students, unemployed or just dodgey drug dealers?
I've noticed this since i'm unemployed at the moment. I couldn't really get anything even half good together (in terms of making full tracks) for 2 years when I was working 9-5 in a pretty hectic job environment.
As a side note, some people progress further than others easier. Some people really 'get' the sound design aspect of it and can bang out beautiful patches within weeks/months of picking up subtractive synthesis for the first time.
Been producing "music" for 3 years, while in reality 98% of that has been sound design.
Some people are not very good at either of those but have a fantastic ear for music.
Savant is a good example
Some people are awful at everything and take years to even finish a track.
I'd say this is half true for me. I might first use 2hrs for drums, then get some melody going, then decide that drums weren't good enough, so make another set = another 2hrs. Now the synth patch doesn't work well enough with the drums for me, so i'm gonna make a new one etc. etc. etc. after putting 8hrs on the track my mood has changed so i don't want listen to the thick layered lead made from 5 different patches, so I start over to make completely something else.
In the end, every track i've finished, is finished only because i forced myself to it and that means the quality and arrangement ends up being crap (e.g. chorus 2 being exactly same as chorus 1, no any exciting fx's or fills, mixing with only headphones, squashing track to death...).
I still enjoy it tho.
