Roles change faster than people, and executive tenures are often short. In cases of true rapid scale (a business that’s 3–10×ing every year), I tell people to expect leaders to last about 18 months. Let them surprise you by lasting longer, but don’t let it surprise you if it’s shorter.

You should find the candidate confusing at times. If you first see their dysfunction, you should know you have yet to find their genius, and vice versa.
