Fighting for perfection/ fighting against imperfection.
No matter how much we struggle to reach the first, we lack always behind it. No matter what we do to keep ourselves away from the second, we will never make it. It is always there; like you are shadow. What is necessary is to do your best/just work hard to be the best possible. When it comes to a person. It is not really about being perfect, or looking for the perfect; in other words, someone exactly as you are. Rather, you look for the best human inside anyone's self. Sometimes, they just make excuses saying that I am not perfect. But come on! You are not supposed to lie to me, because you are imperfect.
This very concept of perfectionism is meant to test one's humanity and to what extent we are able to develop ourselves. We are living an age where in people just make excuses. They do not do it right, which is not problematic; but, they do not even make an effort, or make change.
It is your life, stop making excuses and go ahead. Errors are just signs of learning. Yet, it is mere stupidity to take the same procedures and wait for different results. You are not perfect, you are not meant to be. Yet, you are meant to keep it up and do your best.
