What question made the biggest impact on your life?

What can you - as an individual - do to have a positive impact on the world?

Before I had children I had simple ideas.  Recycling, turning of the lights and riding my bicycle.  Later I realized this was a somehwhat selfish, fluffed up show for others.  None of what I was doing directly touched another person.  Sure, it helped out with my personal carbon footprint, but I can't say it did much else.

Now, as an older, more informed (I refuse to use the word wiser, because that just isn't true) I realize there is a lot more for me to be doing.  As much as sometimes I would rather not, I'm going to have to "get my hands dirty" and deal with stituations and people that aren't always so pleasant.  This is going to be the most effective way to create change in our world, more direct and invovled rather than passive as I was before.  Its all because of my children, well any ones child, really.  Such a driving force, those beautiful little faces!
