One cannot strive for perfection without losing a part of oneself. Life is full of changes that affect us every day. Once a person decides to change consciously, the views towards various circumstances will also change. You develop new opinions and realise things that may have been hidden from you before. However, those who strive for perfection will inevitably find that life will respond accordingly. It is like a fight against oneself, which is always furthered by external circumstances, for the positive as well as for the negative. The problem is that you cannot simply erase the past. Much remains in memory, even after a long time. If you start to declare your own past as inferior out of your own conviction and the feeling of superiority, then you should better ask yourself what circumstances made you who you are in the first place.
