Here’s number 7 on my list.
7. Stop blaming other people.
Everyone blames someone else at one time or another. Nobody's perfect. And you may even be thinking, "But it WAS my spouse's/parent's/boss' fault that I missed my plane/don't trust others/don't make enough money."
And it very well may be, but the key to living a long and happy life is knowing how to accept personal responsibility and not blame others -- even when it may be their fault. This does not mean you have to go through life letting others walk all over you. On the contrary, accepting personal responsibility means you have to take the high road and be the bigger person, even when it's hard.
