This the real world, homie, school finished They done stole your dreams, you dunno who did it.” — KANYE WEST, “GORGEOUS - Ben Horowitz

Write down the strengths you want and the weaknesses that you are willing to tolerate.

When things go well, the reasons to stay at a company are many: Your career path is wide open because as the company grows lots of interesting jobs naturally open up. Your friends and family think you are a genius for choosing to work at the “it” company before anyone else knew it was “it.” Your résumé gets stronger by working at a blue-chip company in its heyday. Oh, and you are getting rich. When things go poorly, all those reasons become reasons to leave. In fact, the only thing that keeps an employee at a company when things go horribly wrong — other than needing a job — is that she likes her job.

Because your culture is how your company makes decisions when you’re not there. It’s the set of assumptions your employees use to resolve the problems they face every day. It’s how they behave when no one is looking. If you don’t methodically set your culture, then two-thirds of it will end up being accidental, and the rest will be a mistake.
