William Arthur Ward

 Curiosity is the wick in the candle of learning.

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.

A warm smile is the universal language of kindness.

Feeling gratitude and not expressing it is like wrapping a present and not giving it.

The pessimist complains about the wind; the optimist expects it to change; the realist adjusts the sails.
