Learn to separate people from their actions.
If you do this, you’ll find it easier to forgive when others hurt you. For someone out there, it might be a parent, former spouse or former colleague that hurt you really bad, forgive him or her.
I am not saying that you need to find your way back into that person’s orbit and be lovey-dovey with him or her, no. But you need to release them from their deeds because people are not their deeds. If they knew better, they’d have done better.
