If you want to be great in life, you have to suffer a lot. The discipline of pain and suffering is the only way in this world, to evolve into a higher state of human development, physically and mentally.
I am not talking about self-mutilating, like people who beat themselves up in order to experience pain. That's a mental disorder. What I am trying to say is that the activities and things in this world that lead to mental and physical greatness require people a daily regular routine, all year long of being able to experience some kind of physical and mental pain (for example: exercising outside in a 35 degree temperature, preparing and cooking your keto low-carb meals in your kitchen, like cooking chicken, shredding cabbage, and reading and studying a lot, hunger pangs between meals, And lifting heavy weights) These activities are not very painful, like breaking a leg, but they require some kind of moderate low levels of pain.
Compare those activities, with eating pizza, eating at restaurants, because of being too lazy to cook, not running or exercising outside at all because of fear of painful cold weather, not studying and not reading at all, and instead watching movies or playing video games. And being sedentary and not exercising at all. These activities even though a lot more pleasurable, will lead to physical and mental inferiority and not to greatness
Most people think that they can be great the easy way, the lazy comfortable way without any pain at all. Like by owning and driving expensive luxury vehicles, expensive cell phones and the other toys and gadgets. But those are externalities outside of our body and mind. That are not part of our selves, people in this modern world think that they don't need intelligence and physical power at all. All they need is to hide their decadent physiologies inside a car, or escape reality thru a cell phone (What a stupid society)
But really there is no way in this world to be great, the easy way. If you want to be great you have to be prepared for a life of pain, strict discipline a lot of will power
"To those human beings who are of any concern to me I wish suffering, desolation, sickness, ill-treatment, indignities - I wish that they should not remain unfamiliar with profound self-contempt, the torture of self-mistrust, the wretchedness of the vanquished: I have no pity for them, because I wish them the only thing that can prove today whether one is worth anything or not - that one endures."
(The Will to Power, p 905)
"You want, if possible - and there is no more insane "if possible" - to abolish suffering. And we? It really seems that we would rather have it higher and worse than ever. Well-being as you understand it - that is no goal, that seems to us an end, a state that soon makes man ridiculous and contemptible - that makes his destruction desirable. The discipline of suffering, of great suffering - do you not know that only this discipline has created all enhancements of man so far?" -(Beyond Good and Evil, p 225 )
"I do not point to the evil and pain of existence with the finger of reproach, but rather entertain the hope that life may one day become more evil and more full of suffering than it has ever been." -Friedrich Nietzsche (1844-1900)
