Once you grasp what you're actually capable of and what your potential is as a person, it all becomes clear. You don't need to be a genius, your don't need to be gifted, you don't even need to have the credentials other people look for in order for you to be the best you can be, right?
I'm sure there are times when you think you have to tone down and follow the norm—sure, that works for others but if you want to lead, and you want to build yourself into a pioneer who looks ahead rather than stay in the comfort of the "norm", there are other ways to move forward.
