When others take advantage of you,...

"When others seem to take advantage of you, do not retaliate by trying to take advantage of them. Use your power in improving yourself, so that you can do better and better work. That is how you are going to win in the race. Later on, those who tried to take advantage of you will be left in the rear. Remember, those who are dealing unjustly with you or with anybody are misusing their mind. They are therefore losing their power, and will, in the course of time, begin to lose ground; but if you, in the mean time, are turning the full power of your mind to good account, you will not only gain more power, but you will soon begin to gain ground. You will gain and continue to gain in the long run, while others who have been misusing their minds will lose mostly everything in the long run. That is how you are going to win, and win splendidly regardless of ill treatment or opposition."
