Helping people... now that we are older...

I use to enjoy helping people, I guess when I was younger, the thought of an opportunity to do the world some good plus building a stronger bond with another person was the most awesome idea... Now it seems like everybody that you don't know who ask for help are just about using you to get what they want. And then when you see other people get burned and situations where helping someone can get you into trouble, you start being guarded and questioning if you should help them at all... and then you ask yourself "what ever happened to the goodness you had in you before?" It was all good before... when we never questioned motives and selfishness, and it sucks that we question it now... but we have to; to protect ourselves and survive. shrug nothing we can do about that. But I still go on my instincts and help those I believe need it, and if I got to lose a few, so what, in life, you win some, and you lose some... just don't expect to win them all, and live humble.
