You can't change other people. Instead, what you can do - change yourself.

Adjust your expectations.

DON'T GO WITH THE FLOW, go with what suits you the best.

Stay away from people who you think are bad for your well-being.

Manage your time and other resources according to your very own needs.

Never let anyone decide and affect your emotions.

Do something about it if something goes wrong, instead of whining.

Afterall, you are the one that should be held responsible for your own life.

It's simple, yet some people simply can't understand it.
