Your role has changed again, but there is no one to tell you what your role is or how to perform it. The rules of survival and success have not changed, because there are no rules, you have to make the rules yourself. Your challange is to make the right rules.

You need to be persistent and focused, but you are past the need for deep resilience. Complaining about your intense travel schedule does not count if you travel first class around the world: you are showing off.
