Do we have to grin and bear it? In that moment, aside from stopping whatever it is we are doing, can we do anything about it?
If it is something we have to do and that we want to do, then we have a choice to be positive and grateful. This will make space for what is possible. Doing it through gritted teeth closes us off from all possibilities.
Next time you are doing something with gritted teeth, relax the jaw, take a deep breath – inhale all the possibilities and exhale the tension.
