There is a famous Buddhism saying – you will not be punished for your anger, you will be punished by your anger. It was a misquote and not said by Buddha, but none the less, it is beautifully misquoted. Anyway, the older you gets, the wiser your EQ supposed to be. The best revenge is not to lash out your anger if front of the person, the best revenge is controlling your EQ and letting go. I disagree on the best revenge is to be successful, this is an indirect form of revenge, it will consume you as you focus your entire life and precious time on seeking an indirect revenge on your boyfriend or girlfriend.
