Does it have to be either or? Does it depend on the context? Could a balance of both spur on better performance?
I think a lot of folks spurn the idea of being motivated by fear. But in some instances, I think it can be a positive motivator.
Take public speaking, for example, the nerves in our stomach before the presentation can be harnessed to lift our energy to new levels.
I remember feeling all sorts of fear when the players on the opposing rugby or football teams looked bigger, faster, and stronger than me. But I could use that fear to shy away from the challenge, or to turn up in a new way.
Success is a better motivator, but a sprinkling of fear can lift our game.
