Although I have many opportunities for much higher pay and much more interesting work, I have developed a confidence problem. I think that problem is due to my having stayed way too long and not having much challenge to overcome.

However, as the article says “If fear has caused a person to be professionally risk averse, no new challenges will come his way unless or until he sticks his neck out.”

Also, as Jordan Peterson has opined, “There is real adventure associated with being called to move forward into the strange and the unknown. To see yourself able to do do that is the right tonic for self esteem.”
