Knowledge and capital matter a lot, but you are forgetting another crucial factor which is luck. No amount of luck and knowledge can help you achieve success if luck eludes you.

Personally, I feel that luck is the most important factor followed by knowledge followed by capital. Why? Because it's possible to earn huge amounts through small amounts as long as you are smart and luck should favor you.

Gambling Example: Winning an accumulator or parlay can help you earn huge amounts by risking small amounts.
