NEVER complain about your work

It puts food on your table. You and I and no one would survive without that.

If you work has put you in a place where you are complaining, pause for 15 minutes, step away from everything, perhaps in a nature walk, and think how you can solve it.

Complaining is for people who love being miserable more than responsible. Misery makes you a victim. It relinquishes the responsibility of you having to make a change.
Responsibility makes you a master. It reminds you that you are in charge, even when you are not.
