You'd all seen or heard of the movie Pay it Forward right? Now what I'm suggesting isn't go out and change 500 lives by doing some drastic act for the good of mankind. No fiery protests, no giving your life savings to charity.
But try something for me. Today or tomorrow or in the next few days, do something for a stranger. Pay the bill for the person behind you in the drive through of McDonalds or the toll of the few cars behind you in the toll lane. Give that homeless man/woman you pass everyday a few dollars. Smile and hold the door open for a few people coming in at the same time as you somewhere. Find a journal or a profile here (preferably same gender or sexual orientation as yourself so it doesn't backfire) and just say something like "hi, just wanted to say I loved your profile and/or your picture. No response required. Not hitting on you. Just wanted to let you know. Hope you have a great day." Smile at that woman with the noisy kids and say "I've been where you are. It gets better" in the grocery instead of complaining loudly to make sure she hears it.
Just.... do something. Something that spreads the joy, that makes the people you do it for feel good that day. Then come back here and tell us how it made you feel.
We may not change the world, certainly not if it is a one time deal, but as sappy as it sounds (though those who know and like/love me deal with this nasty trait of mine, poor souls), maybe we can change somebodies viewpoint for a moment. Possibly even their life. Maybe even our own.
