Edmund Hillary was one of the first climbers confirmed to have reached the summit of Mount Everest. He was quoted as saying, "It is not the mountain we conquer but ourselves." Such a person who can conquer himself or herself has great power. They can accomplish their goals. How can we conquer ourselves? First of all, we should unchangingly keep what we say, and do what we have been determined to do.
"He who is slow to anger is better than the mighty, and he who rules his spirit, than he who captures a city" (Proverbs 16:32).
