Many times people are simply attracted to the idea of being an owner of business instead of working for someone. But like someone else pointed out, you will probably end up working more than if you were working for someone and it is not necessary that you will be earning more than you would if you were working for someone.

I have seen both sides of the coin and it does take a lot to have a successful business. It's only a matter of how much return on investment you get from your business. Some business take years and years before they start becoming profitable and before your investment is even returned.

If you make enough money working for someone to live a comfortable life it will be a big change for you to have to constantly be on your toes till your principle investment is paid back.

Good luck
