Seek Out Your Limits (and Push Through)
It’s difficult to make this one sound like something other than one of those cheesy motivational posters for your office. However, this relates more to accepting discomfort than some vague and useless metaphor about rock climbing.
Mental toughness grows when you act bravely. On a daily basis, acting bravely often simply means seeking out things that make you uncomfortable, like public speaking, learning new skills, making toasts, or starting conversations with strangers.
You can practice this type of lowercase “b” bravery at home or at work on a regular basis. You simply need to engage a problem or begin an activity that is outside your “comfort zone.”
Mental toughness usually means engaging the unknown. It doesn’t mean that you have zero fear, but that you’ve acquire the skill of coping with fear.
When a problem arises, even when its outside your area of expertise, try to solve it yourself before immediately handing it off to someone more qualified.
In fact, bravery isn’t necessarily an attribute you’re born with, but a life skill that anyone can develop.
