There's physical adversity, that if you are someone that likes exercise like I do, I exercise everyday. When you exercise, there's pain involved and so you're putting yourself through adversity in that situation. It's never totally pleasurable and there are moments where it's kind of boring or painful and you know that in doing that, you're making your mind and body tougher and more resilient. So must be able to deal with the boredom that happens in life. - Robert Greene
