make people feel good

This is a hard thing to measure. But little things can mean a lot. Some possible, little ways to do this include:
> remembering people’s birthdays
> remembering people’s names
> surprising people with out-of-the-blue gifts
> responding to e-mail quickly
> sending handwritten letters and postcards to friends & strangers
> donating money to charity

more ideas on this topic? would be much appreciated.
