Try to make at least one person happy every day. If you cannot do a kind deed, speak a kind word. If you cannot speak a kind word, think a kind thought. Count up, if you can, the treasure of happiness that you would dispense in a week, in a year, in a lifetime!
Any fool can try to defend his mistakes - and most fools do - but it gives one a feeling of nobility to admit one's mistakes. By fighting, you never get enough, but by yielding, you get more than you expected.
