There’s no doubt, fear can be a useful emotion: it stops us doing bloody stupid things like leaping off a tall building, trying to fight a lion with our bare hands, or dangling our dangly bits over a tub of scorpions.
But sometimes, fear is restrictive; fear holds us back from doing things that are not dangerous, just outside our comfort zone. Fear of failure, fear of embarrassment, fear of not living up to expectations. And if we never push ourselves to overcome these fears, our lives are duller, more restrictive and ultimately unfulfilling.
Some fears, then, act as a warning, while others stifle our growth.
The problem is not always knowing which are which.
