Sometime the stuff you do may not make a difference to the world, and people may tell you that, but as long as you know that you made a diffrence to someone some where it really should not matter what other people think. It may be the smallest thing like giving to a homless but at least you know you have made a diffrence to that person.
I once gave money to homless and my cousin had told me what for that it was just a waste of my money. Just then had i realised that it wasnt a waste of my money because he now had money to buy a decent meal. After that I have been thinking that maybe I could go and do more like help at a homless shelter, all I have to do is take one step at a time. I just read on this website that they are wanting to make some sort of law in Miami that if they find you giving to a homless they arw going to give you a fine of 300$.
