I might be able to save you reading Grant Cardone's book The 10x Rule http://amzn.to/2E3NzQK .. he basically wants you to be more productive: immediately massively productive. Stop thinking about things and just do them.
Thinking is fun and all, but doing stuff is pretty much all that matters and if you do lots of things and some actually work, that's at least as good as thinking about it and trying to guess ahead of time what might work.
As he says "while others are trying to figure out how they will get something done, you will have already finished it."
Perform now, not later.
