The trick is understanding the difference in expectation and reliance.

Expect other people to do their job, but always rely on yourself to get yours done. It’s not your fault if someone else doesn’t do their job (unless you’re their manager whose sole purpose is to ensure your employees can and do perform their job….but that’s a different discussion).

Relying on other people to make your life better is not a good way to have a good life.

There’s significantly more nuance than what can fit here, but that’s the gist. Take care of yourself, don’t rely on and expect other people to do it for you.
