Reflections from a thesimpledollar.com article (http://bit.ly/diWt2b).
Things that are a waste of time or money is defined by you, not others! Anything you give time or money to that adds value to you or others IS NOT a waste.
Remember that there are some activities when done by you will add value to you, but when done by somebody else, will not add value to them (because of their different system of values or priorities).
Don't let them define what is a waste of time and money for you!
