We are not here to suffer, and suffering doesn't make you stronger. Strength is a survival instinct, not a natural desire, and suffering, as much as it's partially a choice of perception, makes you weak, if anything—physically weak, as health problems start developing due to stress, mental illnesses begin to occur, heightened emotional unavailability towards yourself and others, depressive perceptions of the world, and so on.
All these are coping mechanisms of severe pain because your brain is so desperate to survive that it sends all sorts of signals, even if it means giving your suffering some sort of meaning through the use of your ego.
But the truth is, it's not necessary. We are here to just exist, to experience this earth, and to do our inner work to raise our internal vibration to a state of love and awareness, literally.
