"Since hate poisons the soul, do not cherish jeolousy. Avoid people who make you unhappy."
Here I am continuing with the 8th out of the 12th commandment of life. :)
It is never a good idea to compare yourself with others. Be happy with who you are and what you have. You are unique. You are special.
Do not be envious of your sibling, friend, colleague, neighbour, classmates etc. Use your energy to improve your own life instead of wasting your life in miserable envy.
