6. It's not my fault
Blaming others for things they did or didn't do is one of the weakest and easiest things to do in the world. Blaming is easy, because you don't really have to do anything other than tell people how they made a mistake and how they shouldn't have made that mistake instead of trying to help someone. Don't be that person, the person who just always tells people what they did wrong, we all make mistakes, so do you, learn to accept your mistakes rather than blaming others for them.
5. I can't forgive them
Yes, you can and you will. Holding grudges against people is the root of a lot of negativity in your system and you definitely don't need any of that. Yes, I understand, they hurt you badly and you can't forgive them. Don't do it for them, do it for your own self and salvation. Try forgiving them for the mistakes they've made, you'll find yourself at peace, you'll find yourself relieved of a lot of stress and weight, be the bigger person by forgiving them, not only will you be happier and healthier, they'll remember how loving you are and will think thrice before hurting you again. If you want to be successful in life, you need to be a positive person. Let the negativity leave your system, let go of the grudges.
