We all deserve respect, never allow anyone to put you down.
People can't just bring you down, but they can determine who you are if you allow them too. Don't let someone determine who you are through his/her incorrect expectations. Don't let people limit your potential; instead, prove them wrong. All successful people were rejected lots of times; they failed over and over again, but they always refused to accept people's expectations of them, and they refuse to give up. Despite your failings, we all deserve respect, never allow anyone to put you down.
