Mental resilience is trained.
It is practiced.
Like all else of virtue.
You must fortify your mind against negative thoughts.
I can’t even remember how it feels to doubt myself.
When you realise that what you have been taught all your years growing up via educational institutions is all just a narrative that "they" tried to propagate ,it is very hard to resist timeless principles, the truth, which works in conjunction with your mind and concious.
