Learn to forgive those who hurt you. Easier said than done, I know. It may be hard not to hate the person who’ve caused you a very deep cut but you will never be free from something unless you accept the situation and forgive the people who caused it. Don’t stress over the things you can’t change.
You can’t please everyone. Not everyone will like you, there will always be people who will say something about you no matter how much you try to please them so just be yourself and do what you do. As long as you’re not doing anything bad, keep going.
Try to understand others before you judge them. Stop judging people for the things they do for you do not know what they’re going through. Put yourself in their shoes first.
Accept your mistakes. Always accept your mistakes and apologize for the damage you’ve done.
You won’t get everything you want. It is not because you do not deserve it but because you deserve something else, something better for you. You just have to fully accept that not everything you want is good for you.
