If I were to start taking care of my grooming, I would no longer be my own self... so the hell with it... I will continue to be unconcerned about it, which surely has the advantage that I'm left in peace by many a fop who would otherwise come to see me.
I should never have made my success in life if I had not bestowed upon the least thing I have ever undertaken the same attention and care that I have bestowed upon the greatest.
