Years ago I read a book of J Krishnamurthi where he explained that Fear is jewel.
Fear and confidence arise out of assessment of risk, danger or an obstacle.
A fear warns us: Get out from here. Get help.
Over confidence says: Nothing to worry. I can fix this. I have fix any such things in past.
Fear has saved many lives. Over confidence has killed many a lives.
