It is very wrong to assume that some people are successful in what they do because they are lucky.
One of the signs of humility is the willingness to learn, which comes from understanding that some know what you don’t know.
From my personal observation, people who seem to be on one spot without significant progress, usually have a friend or colleague who can help them nearby but pride prevents them from asking for help.
You will always have to choose between learning from a colleague who is ahead of you, or competing with him, at the risk of frustration which leads to bitterness.
But if you humble yourself and learn from that phase of your life, who knows if the people who help you today are helping you into a position from where you will help them tomorrow.
Pride will always keep you from seeing the big picture because you are focused on yourself.
But God gives grace to the humble.
