When you lead your real job is to create more leaders not more followers.

When you take a job take a long look at the people you’re going to be working with—because the odds are you’re going to become like them; they are not going to become like you. You can’t change them. If it doesn’t fit who you are, it’s not going to work.

Don’t be a hero
