And on the lighter side:

Just a little philosophy to start the week:

It takes a wise man to learn from his mistakes, but an even wiser man to learn from others.

If you understand, things are just as they are; if you do not understand, things are just as they are.

When the character of a man is not clear to you, look at his friends.

Water and words... Easy to pour, impossible to recover.

To know the road ahead, ask those coming back.

You will not be punished for your anger; you will be punished by your anger.
