Doing something worthwhile!

I am a person who always thinks that our lives are wasted if we do not help the disadvantaged in some way or other. But I have just realized that I have not done anything significant for the disadvantaged in the past few years. I have been caught up in the daily grind and have lost my focus. The place where I am does not offer many such opportunities and its hard to just while away time without doing anything worthwhile. I think I should seriously think of doing something that will assuage my guilt and provide something worthwhile for the humanity.. I have some ideas. But lets see how that works out..
