William Arthur Ward, is one of America's most quoted writers of inspirational maxims... (wikipedia)

The pessimist complains about the wind; the optimist expects it to change; the realist adjusts the sails.
If you can imagine it, you can achieve it. If you can dream it, you can become it.
Flatter me, and I may not believe you. Criticize me, and I may not like you. Ignore me, and I may not forgive you. Encourage me, and I will not forget you. Love me and I may be forced to love you.
Feeling gratitude and not expressing it is like wrapping a present and not giving it.
A warm smile is the universal language of kindness.
