Am I Sure?

Since I was about 10 years old, I had a confidence that I was chosen by God to do great things. I did not know what I was to do, say or accomplish, but that feeling never wavered. Am I delusional? I think not but do not know that or anything else for sure. Am I just vainglorious and self-congratulatory? I think not. I believe that my sense of elevated, exceptional, august self-worth is realistic and that I am what I claim I am. I cannot prove or disprove this feeling of greatness in my soul but perhaps it will be validated should by my bhavior in the public eye.
