For the rest of your life to be as meaningful as possible, engage in spiritual practice if you can. It is nothing more than acting out of concern for others. If you practice sincerely and with persistence, little by little, step by step you will gradually reorder your habits and attitudes so as to think less about your own narrow concerns and more about others' - and thereby find peace and happiness yourself.
Dalai LamaThe way to overcome negative thoughts and destructive emotions is to develop opposing, positive emotions that are stronger and more powerful.
Dalai LamaCertain beliefs must accompany every action: One should act without selfishness, cultivate compassion for all living things, and develop respect for others.
