“That which does not kill us makes us stronger.” ― Friedrich Nietzsche
I don’t think people should go through traumas. I don’t think it’s necessary to go through lots of pain, sufferance, difficulties to be a good person.
On another hand, living with everything you want at your disposal, no stress whatsoever, no limitations nor boundaries, being allowed to have, do and experience everything – I also don’t think that is the right path.
Tough experiences should be avoided. But a minor inconvenience, a limitation, a self-imposed limit, a boundary you choose not to cross – this might make you a better person.
