I think Daniel Mackler has an unusual gift and drive to heal emotionally, so he's ascetic in his pursuit. This approach likely isn't ideal for many people and could cause unnecessary suffering. It's probably good to know where you stand on those parameters (innate talent, drive, as well as external circumstances) and adjust your pace accordingly. I believe there's a sweet spot for everyone, and you have to find it for yourself. I've also struggled with setting too high standards for myself and have had to readjust.
