The choice is yours, even when you are told it isn't

No one can make you feel inferior without your consent.  Eleanor Roosevelt

Don't allow people to tell you who you are and who you should be.  Don't allow people to tell you what you are suited for and what is above or beneath you.  When you allow people to define you then you have given them permission to control your life.  And generally what happens is when someone else is controlling your life you feel inferior, even if they are telling you how amazing you are.  Because generally they only think you are amazing if you are performing/behaving up to their standards. Once you don't, they don't think you are amazing, they belittle you and push you to be better which leads, oddly enough, to feelings of inferiority.  You have the choice whether or not you will go through life feeling inferior.  If you have given anyone permission to make you feel inferior you also have the choice to deny them access any longer.  The choice is always yours, even when you are told it isn't.
