One thing that founders forget is that after they hire employees, they have to retain them.

It's really easy to get PR with no results & it actually feels like you're really actually cool, but in a year you'll still have nothing.

Share results (financial and key metrics) with the company every month.

Study the unusually successful people you know, and you will find them imbued with enthusiasm for their work which is contagious. Not only are they themselves excited about what they are doing, but they also get you excited

Be suspicious of any work that is not building product or getting customers.

Great execution towards a terrible idea will get you nowhere.

Every thing at a startup gets modeled after the founders. Whatever the founders do becomes the culture.
