When I realised I would be "poor" all my life working for others, and reckoned I should try to pursue my business ideas.... It turned up I already have two kids and my daily costs are too high to leave my current job.
Obviously every alternative has its own (dis) advantages.
If you want other's money you need to convince them. That means a lot of extra work writing plans, and when you receive the money you are inmediately diluted.
For that reason I always pursue ideas I can start developing on my own... And it is then when I find my main weak point: I don't have enough time...
