Identifying what gets you through tough times can help build confidence. If you know that you are strong and determined and can point to situations in your past where you’ve handled struggles with strength then you can draw on that confidence for current struggles.
This is What You Need to Prepare for Tough Times
Debby Germino

What happened to you — your experience — is like a pile of rock from the California gold country. It has untold wealth in it, but as it is, it does you no good. Mining your experience for what you’ve learned and what your strengths are is how you get to the incredibly valuable knowledge that will help you not just survive, but actually thrive in your life.

Better yet, you do this work once, and it will enrich you for the rest of your life.
