Indeed acceptance is very substantial way and key through building confidence and learning appreciation of oneself!
I used to compare myself and had gone with so much of insecurities looking at my flaws and impurities. Not untill some people had taught me one thing. Physical attributes, achievements and one’s abilities does not significantly dignify one’s worth, but it is him who can only prove his value by doing things that are considerably good and responsible.
If one could learn to adapt and apply this concept of thinking it would be also much easier to co-exist with people around him while also nurturing his capacity of understanding the self, all the more is to progressions and total actualization.
