I agree capital isn't the first requirement if you want to start a business, I know any business require capital, but if you think capital is the most important, even someone give you $1 Million, you might not taking a step because you don't know what business you want to create in the first place.

But, I'm not that agree with proper management plan, that's mostly for medium to big size business.

For me, skill is the number one, as long as you have skill, you know what you doing and how to execute it.
