How to Scale Yourself Down has some really interesting advice on how to go from leading a team at a bigger company to rolling up your sleeves at a startup. A couple of my favorite quotes:

Avoid process out of practice. Leaders who are successful in a startup are the ones who naturally reinvent their own toolboxes, and question what the process is trying to accomplish before establishing something that might be too heavyweight.

However, process is a double-sided coin. “There’s often an overcorrection when leaders move from big companies to small startups.
