My inconsistency. I may feel one way today and have completely different views another day. Some days I can't stand a person, then I want to give them a second chance. I change my style, my eating habits, and my attitude all the time. The reason I am at peace with this is because of one of my favorite quotes I read in my junior English III Honors class:
"A foolish consistency is the hobgoblin of little minds, adored by little statesmen and philosophers and divines. With consistency a great soul has simply nothing to do. He may as well concern himself with his shadow on the wall. Speak what you think now in hard words, and to-morrow speak what to-morrow thinks in hard words again, though it contradict every thing you said to-day. — 'Ah, so you shall be sure to be misunderstood.' — Is it so bad, then, to be misunderstood? Pythagoras was misunderstood, and Socrates, and Jesus, and Luther, and Copernicus, and Galileo, and Newton, and every pure and wise spirit that ever took flesh. To be great is to be misunderstood." - Ralph Waldo Emerson, Self-Reliance
It taught me that there is no reason to fit a certain mold or standard. Every great person that ever lived has never been completely perfect.
