I'm ok with average, well kind of...

Why do so many strive for perfection or strive to be the best and then get disappointed when we never reach it?  Isn't it safe to say that majority of us are just normal average human beings living our lives day to day never doing anything extraordinary?  I'm siting here writing my final paper and at the end, I just give up, like always, and say welp it is what it is and hit the send button to my professor, never double checking or proofreading.  I'm not beating myself up over a stupid paper, and while I hope for an A, obviously, I say to myself, C = passing!  Yet so many of my classmates miss out on their kid's football games, or hanging out with friends, or constantly fight with their husband because they simply do not have the time anymore to devout to a relationship.  I understand that we set a goal for ourselves, as in my case getting my masters so I can teach nursing, yet most of us fail to recognize that every day, every step we take is a goal.  We need not to forget that life is happening while we are trying to acheive some big goal, whether it be getting a degree, buying a house, or finding Mr. Right.  So I wonder why we become frustrated, stress out, and miss out on what is really important to us while we try to strive for perfection.  Also are we making TOO BIG of goals for ourselves that they are so unattainable and we are only setting ourselves up for disaster and misery?  Back in the olden days, people's goals consisted of having and keeping a job, raising a family, staying alive, having food on the table.  Today people want to conquer the world, want to be the next big star.  Hate to burst your little bubble sweetheart but why not shoot lower, build your confidence a little first, soak in the averageness and sigh a sigh of relief.  Lets face the facts and be more realistic please! And just fucking live your life!
