How often have you heard someone say you should know your limits? That’s bull roar! It’s a precursor to failure.
You have the ability to achieve whatever you put your mind to. You are limited only by the restrictions you place on yourself. Put in a greater effort if you haven’t been able to reach your goal, greater than you think possible. Show the world, more importantly, show yourself that you are not going to bow down to the false gods of illusion.
