You must decide how to use it. If you are methodical logical you will probably devise a plan/schedule of important things to accomplish with it. On that list is REVENGE RETALIATION against those whom you preceive to have wronged you.
What amount of time do you allocate to getting back at? 25%? 50%? 75%? 100%?
If 100% then you prefer to dwell in the past attacking rather than moving forward and building constructing improving. Your choice of course but at the end of your life (you are not given immorality) what will your signal signature contribution to the world have been? What will your legacy be? How will you be remembered? What will your epitaph read? "He got back at everyone who ever criticized him. Job well done." or "He got back at everyone who ever criticized him and thus wasted his entire life getting back at rather tnan leaving something substantive and significant and worthwhile and good as his legacy"
You got the power. You get to use it however whenever whyever as you see fit. How would you use yours? Why?.
