Selflessness
Always show your willingness to help your peers, even to the extent of putting them before yourself. It is much better to build a reputation as a selfless, giving person that aggressively pushes themselves and everyone else up instead of only themselves.
Competition is good, but drop any desire to ‘beat’ the other person in your personal interactions with them. Always demonstrate authentic selflessness and a desire to see the other person succeed.
Stop treating your career as a zero-sum game. Drop the idea that you need to beat everyone else and keep your knowledge and ‘secrets’ hidden to maximise your job security.
