The incidents and the experiences impact our lives and build a perception & identity of our own.  Imperfection and impermanence is inherent to being human. Learn from them and take life less seriously. Fear makes us doubt our capabilities thus erode our self confidence and sense of self worth. Embrace your imperfections; no one is judging whether or not you are perfect. Life changes more than it stays the same and nothing lasts for long. Aspire and strive to be best but do not conduct yourself in line with someone else’s expectations. Human mind is deeply influenced by thoughts.  Control self talk that is self critical, remain optimistic and change your mind set towards a new perspective of life to win over the frustration & unhappiness.
