Lots of gems in this post, but my favorite is “focus over features”.

Tom Preston-Werner. Founder, Github

• If you have customers willing to pay before you even have a billing system, that’s a good sign.
• So we have a problem. Then we bring an executive. Now we have two problems.
• Github’s founding team is a good mix. We have 4 vectors: I’m logical and pragmatic, Chris is a product visionary, PJ is great at business and operations, and Scott is doing culture and makes sure everyone is happy.
• What you leave out is just as important. Focus over features.
