Constant kindness can accomplish much. 

As the sun makes ice melt, kindness causes 

misunderstanding, mistrust, and hostility to evaporate.
- Albert Schweitzer

Nobody cares how much you know, until they know how much you care.

I choose to be caring, compassionate and kind toward all people, 

and I also choose to be indifferent to gossip, petty complaints, and idle chatter. 

About those, I just don't care.
- Jonathan Lockwood Huie
