Approach experiences with the idea that you know less than you do. Curious attention and observation can be a vital tool in gaining more knowledge, understanding and wisdom.
Failure is disappointing but it provides valuable insight towards the next steps. Don’t fear failure OR fear discussing failure. Something is only really over when you move on, not when you fail.
In times of crisis stay calm, be honest, practice empathy and diligence. Be adaptable and understand emotions will run high. And NEVER, EVER lose hope.
