Hello,
@kiwipete
I completely agree with you. My greatest "progression" regarding the mental aspect of life has been teached by life itself, not by a specific training.
I chose "challenging" path by travelling a lot (so being far from family, far from Madame) when I was student. It forced me to get out my comfort zone on a very regular basis.
My current job as in financial consulting makes me go from a company to another on a regular basis. Then I have to [re]learn quite often. This jobs pushes me often (too often ?) out of my comfort zone.
From there, it also teached me a lot about stoicism and resilience.
It seems that there is no real "mental training" other life itself. Getting through hard times, then having time to recover from it, as a wave seem to be how mental toughness / resilience.
On a regular basis, maybe the idea of never choosing the "easy" way or committing to challenging (but atteinable) goal may be an option: For instance, I chose to re build my bathroom from zero, I often get down from the public transportation before my destination, I go outside no matter the weather, etc... I think this is also a matter of telling to ourself that failure is not an option. But it does not have to prevent us to learn from failure, even if this is uncomfortable as well.
Kind regards,
Pet'
