From "Why You Should Always Do a Little Work for Free" by Jeff Haden

Another short list from Jeff Haden, giving reasons to Why You Should Always Do a Little Work for Free, in other words, why you should give away some of your effort: 

1. You get to stretch a little - loosen the joints from doing the same thing over and over
2. You get to be scared - helps your remember how fortunate you are
3. You get to be more creative - help someone find solutions within their limited resources
4. You get to do the right thing - helping others is not just good for them
5. You get to be a hero - help someone else out and you become their hero
