Your thoughts will render who you are. Discipline yourself to think only constructive, empowering thoughts and your life will slowly begin to improve. Allowing negative self-depreciating thoughts will only hinder you from moving forward. Negativity has no preference. It won’t matter how rich/successful you are, negative thoughts will accompany you. Happiness in your life depends on the quality of your thoughts.
