Living well is the best revenge meaning. There will always be someone who tries to put you down or hold you back in life, don't let these individuals hold you back and drag you down with them. Live the best life that you can and you will have the revenge that you want without becoming negative or petty in any way. If you make poor decisions or fail to put in the effort needed to be successful then you are allowing the negative influences to win, and you will never get the revenge that you seek. By living well you are guaranteeing yourself a good life, and over time thoughts of revenge will fade away because your life has everything you need and what others think will no longer be important. You will know that you have succeeded and that will be all that matters.
