Perfection is something that is unfortunately almost unattainable. Everything changes, not only us as people but also the life around us. Every person has a wide variety of thoughts throughout the day, but it is almost impossible to constantly direct them along the best possible path. Those who constantly chase after their goals without thinking of their own limits will eventually find that at some point they will have to think about whether some things in life could have been different.
One cannot strive for perfection without losing a part of himself.
