The people talking at your back will stay at your back. They are talking behind your back because they won't be able to talk infront of you. The only hurdle between you and your success can be only you. Because if you pay any heed to negative thoughts or negative remarks from your enemies, then it is your fault because you are dragging yourself down. You have to find the glory in yourself. You will fight back the negativity with a weapon that your enemies don't have. The weapon to conquer your enemies is POSITIVITY. You have to use positivity to fight them back.
Show your enemies your back and just look forward. Those sh*t talkers will always talk shit. You have to live your own life. You have to reach that goal, you have to focus on your goal, you need that determination in your life to reach that goal. You need power and energy for your goals not for those sh*t talkers, losers. You have to keep on going because your success is the best revenge you can have.
Just smile at your enemies and let karma do the dirty work.
