Don’t expect people to do anything for you.
Even if you would do it for them. You are you and they are them; you are different people with different thoughts and ideas. What you would do is not necessarily what they would do. If you want them to do something, then ask. If they can, great! If they can’t, then ask someone else or come up with another plan. No one owes you anything. Just as you can say no, so can they.
If you are helping someone and expecting something in return, you are doing business, not kindness.
Once you learn this lesson, your life will have so much less stress because you won’t hold any grudges for people “not being there for you”.
