Once I asked a very successful man the secret of his success, he smiled and said; "Success kissed my feet when I left small battles for small people." I stopped fighting people who fight just to get attention. I've stopped fighting idiots. I stopped fighting with those who fight habitually. Most importantly, I didn't expect anything from anyone. When hope is broken, there is a void in the heart and you cannot win with an empty heart.
I stopped fighting them all:
for my ideas, for my rights, for my dreams, for my ideas, for my destiny.
It is necessary to fight in life, but choose your battles wisely.
