Get to know yourself. The things that make you come alive. The things that get you riled up. The things that bring out the best in you, and the things that bring out the worst in you.
Maximise the positive things, and make a plan of action for how you will cope when you get triggered. Be prepared in advance, and look after yourself well. By looking after yourself, you are looking after the people who rely on you, both in your professional and personal life.
