It’s never healthy to tie your identity to things. Nothing lasts.

Jobs end. Businesses fail. Projects whither or are replaced. People are fickle, move on away from you, and - is the case with everyone - eventually die.

Don’t fear impermanence.

Mourn, briefly, things that are lost that may not happen again. Celebrate what you have. Have hope for the future and what new things may come your way. Enjoy living, as much as you can, and keep being kind to others.
