My thoughts, and here I really my be so wrong! Surely I over look something – BIG.
1) To become entrepreneur, even a small one, yes, you need motivation, BUT also simply entrepreneurial skill.
2) Most folks grew up in situations that had parents work for some kind or other corporate. It therefore is a skill set that has not been developed by many. If it were --- no one would want to work for corporate. Ever. Corporate is simply a kindergarten for grown ups... I worked there for the better part of my life.
3) In fairness --- before one starves one tends to become entrepreneurial. Just look at beggars, they do.
4) Even starting a Union for beggars has/had been done. Also for thieves and other sundry 'entrepreneurs'.
5) The way commerce has developed is, that people have/had to have, become over-dependant on corporate business. The rich get richer the poor get poorer?
6) Small businesses are talked about lots (E.F. Schumacher's "Small is beautiful" etc.) but as soon as e.g. a trailer with two lawn mowers becomes a proposition, corporate will do it. It's called: Franchising over here.
7) I did say the above to invite lots of constructive criticism, because I myself, after been booted from a lucrative consulting job, was completely out on a limb - and still are.

Dreams are only useful if you can recall how it was done.
9) One may have lots of skills or skill sets (I do), without entrepreneurial thinking and gut-feel, you're still dependent on corporate. If you too old, it's best to just die and not take jobs from the needy younger folks. Corporate totally supports this position.
10) I could go on and on in this fashion but it is not really helpful to be all negative, I do realize that. So let's see.
Let the flaming start, I'll put on my asbestos vest in the meantime,
