Long term thinking is so rare anywhere, but especially in startups. This is a huge advantage if you do it.

A small communication breakdown is enough for everyone to be working on slightly different things. And then you loose focus.

Even though plans themselves are worthless, the exercise of planning is very valuable and totally missing in most startups today.

Founders are usually very stingy with equity to employees and very generous with equity to investors. I think this is totally backwards.

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

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

1 of the hardest parts about being a founder, is that there are a 100 important things competing for your attention each day.
