A very short and intuitive post:
Do you wanna know what's working in a "world-class" startup look like? It a loop over ( Coding -> Beer -> Coding -> Beer -> Coding -> Beer) until you faint. Then you will deliver the demo, get some funding, grow, celebrate your success with Beer and writing some code again. That's why there are "few" females in startups and girls don't like Nerds. This a "Masculine" area, seriously !!
