PASSION ! The number one pre-requisite. Of course, you need to identify a problem/need/want AND work out how to monetize. If you don't have customers you don't have a business.
So instead of wanting to be an entrepreneur, starting being more aware, find a problem that really get's you going, solve it, tell the world about it and charge them when they turn up. Being passionate and making a difference is what's really important, not some label that you stick on yourself to impress people at cocktail parties.
Many people, all more intelligent than I, tried to warn me about the miseries and ills of starting your own business, and they were right in everything they said.
If I could be content with a safe, regular job at a large company, I would do that instead without a moment's hesitation.
Unfortunately, I seem to suffer from some kind of mental illness which makes me cranky anytime I can blame anyone but myself for whatever mess I find myself in.
