Volunteer.

Volunteer. There is nothing like the act of giving to those in need to make you feel appreciative of the life you lead. Walk dogs at an animal shelter, feed the homeless at a food shelter, teach English at a literacy program, or assist in programs for special needs children. Do your research and you will surely find a group that can use your talents and skills. If time is an issue for you, contribute through donations and you could evoke the same feelings of happiness.
