Forgive and Move On

If you really want to grow then learn to Forgive...and move on.

To many people hold grudges and use most of their energy toward getting revenge.

If someone hurts your feelings or does something that you do not agree with be honest with them and tell them. Don't yell it at them or bring it up in a argumentative sense but simply tell them your feelings.
Then move on.

Either they will acknowledge them and apologize or they have their own agenda, in which case you still do not need to expand your good energy toward " getting back " at them.
Let it go, do not lower yourself.

When you lower yourself in their arena - they win.

Be better than that- hold your own - as long as you feel you are doing the right thing and you are not hurting anybody and you are truly doing your best- move on.

Now that said , sometimes after the initial contact with a opposite opinion maybe you should soak it all in and be sure that it was not YOU being stubborn or wrong.
Admitting our own false is much harder then admitting other people's false.
Sometimes by you admitting you were wrong you can help knock down the walls and start to build a better relationship.

In other words- Another words sometimes you can win by losing.

At the end of the day you want to be able to know that you did your best to build bridges not knock them down.
