Your always helping friend may make you weaker. Your always attacking enemy will make your stronger

You can safely ignore your friend's invitation, but not of your enemy's.

To understand your weaknesses, you will have to appreciate the strength needed to overcome them.

All of your good friends are like steps in a ladder. With one missing, you would have hard time to go up

Love is not valuable more than friendship. No sir. Love is always in need of taking. Friendship indeed is a giving.

If you don't help yourself, chances are nobody else will.
