I believe there is a line in the Christian texts that says, " Faith without works is dead." It is not enough to light our own candle and see to our own paths. That is but a first step on the journey. It is also our job to spread our lights, by lighting other's candles.
Mother Theresa is one of my heros, even though I am not now, nor ever will be, a Christian. She saw a need, a desperate overwhelming need in the world. People wondered why she bothered tackling such an impossible problem. But her one light, her sincere drive and passion to better the world set fire to so many hearts languishing in the darkness, and through those lights, her divine love spread and grew throughout the world. She was one small person, with great compassion. She did not seek fame, glory, money, power... none of those things. She wanted to ease suffering.
Do one good thing a day and see what happens. Do it even though it may not benefit yourself. Let someone merge in traffic, say something kind to the people no one notices, like the fast food worker, the grocery check-out person. Be kind. Spread what is good to spread. you will not only enrich yourself, you will never know what good thing you have started. Pay it forward.

It's important.
