Why I hate people who complain

I dont really understand why people complain, if there is something wrong with you or in your life then why don't you fix it? But instead your sitting there complaining about whatever the minuscule problem is that you have going on. Stop complaining and go fix it, you can't just keep waiting around for someone to come and fix your dumb little problem, you have to fix it yourself. People who do that are so weak and disgusting to me. Pick yourself up and get it done, because by doing nothing you are not getting anywhere with yourself.
