Going down
Expect dowturns in your career. Build your resilience before you need it. Learn how to de-catastrophise any event, collect credibly optimistic scenarios in advace. Practice letting go negative thoughts and emotions contrary to fighting them. Deflate your ego as much as you can. View bouncing back as a project. Set yourself process goals that you can control instead of outcome ones that you cannot. Be tenacious in the face of rejection. Remind yourself that the tough time you are going through is most certainly temporary (like life itself).
