For me, the key is to decouple my personal emotions from work. Now, I still get angry about mismanagement here and there, but I also set things up such that I can easily remove myself from the situation if things get to the table-flipping point.

The two main practical steps I'm taking right now are (YMMV):

1. Save/invest 50% (or as close to that as I can manage) of what I take home. This is about more than just living jobless for a month for every month I work. Barring catastrophic expenses, if I keep investing this money over ~14 years in a fund that averages 7% return a year, I will make around enough money to support my lifestyle passively, at which point a salary stops mattering and I can financially afford to leave any job, any time.

2. Build my resume with "extracurricular activities". In my case I'm earning an online master's degree on top of work (years of step 1 helps me afford this, and my program is relatively cheap). This makes it easier to find new, interesting work in advanced fields (and it's also just fun to constantly learn new things).
