Looking back

When I look back on my life I get mad and sad. Because I hate who I was in the past. I just realized this year that sometimes I was not the most kind person in the world. Because of the influence one of my "friends" in the past gave me. But this past year I have worked on myself and now I am one of the nicest people around. I'm also mad at myself in the past for being so annoying and awkward(I've worked on that to). Why does the past have to be so humiliating. There are many times I wish someone invented a time machine already. But I just have to learn to put it all behind me and work on my future.
