Thing is you needs to master so many different applications, and there are so many different approches, it would take 3-6 months to do it properly.. and by the time it was complete, there would be newer version of half the utilites, and much would be outdated.

And even with instrusctions, it STILL takes months to learn properly.. example: I've been modeling in Lightwave now going on 20 YEARS, and I STILL learn new tips n tricks, and technicques ever week.. and that's JUST modeling.. the same holds true for rigging, uv mapping texturing, mat creation, morph creation, morph injecting, conforming, ect.

The reason you see so few people really doing it "all" is because it takes constant relearning, and a LOT patience and time incvestment, even if you KNOW what you are doing.

Example: I just finished a clothing set with 7 figures in it... and that took full time (not counting 10-12 hour days)  6 over full weeks to create.
 
And there's no way you can master 20 different applications to create something in a short period of time. if I could I'd be rich myself and retired.

Way too many people take way too many things way too seriously.
