I love my life now. I've got no really big problems except deciding what to do as far as my future is concerned. I'm very optomistic and ready to meet life head on. To be honest there is hardly anything I would change in my life right now, because I love how things are going. The only thing I would work on is getting into an honest relationship, but this isn't the relationship advice thread, so I won't bother you with that.
If your life doesn't seem to be great, I say just be optomistic, chances are it'll get better. If you focus on making it better.
Sorry to be the overoptomisctic guy here, but you know, That's Life.
