This is true @curamax but as you mentioned and evolved - we should always strive to improve in every aspect up to our potential and to change for the better, without being Egotistical, this is my thought.
Make mistakes but try to limit them and to learn each time, what I realized even for myself, and this is also very sad - people "never" (rarely) change.
We need to change for our close people if we hurt them and to look deep inside ourselves and sit down and think how to improve, what helped me in this a lot is self reflecting and also being more in the moment, being present, without distractions and let go of fear and be relaxed.
Nobody is perfect but we need to try to be as perfect as we can be in my opinion, we can always work on each aspect of ourself.
