Once your product is working, switch from not caring about this to caring about this a little bit.

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

Unfortunately the trick to great execution is to say no a lot.

Just put a little pin in your mind: when you cross 50 employees, there are a new set of HR rules that you have to comply with.

If you don't need it yourself, and you're building something that someone else needs, realize you're at a big disadvantage.

If you want something in a deal, just ask for it.
