Brick walls are there for reason. And once you get over them-- even if someone has practically had to throw you over-- it can be helpful to others to tell them how you did it.

No job should, be beneath us. And if you can't(or won't) sort mail, Where is the proof that you can do anything?

I'm sorry. It's my fault. How do I make it right?

No matter how bad things are, you can always make things worse.

Be willing to apologize. Proper apologies have three parts: 1) What I did was wrong. 2) I'm sorry that I hurt you. 3) How do I make it better? It's the third part that people tend to forget. Apologize when you screw up and focus on other people, not on yourself.

Find the best in everybody, no matter how long you have to wait for them to show it

There are respectful, considerate things that can be done in life that will be appreciated by the recipient, and only good things can result.
