He is a straight A student, his family was probably not the richest but they can afford a luxurious lifestyle. What could else could he need? He has the ultimate life 'it' life you would call it, or not. Dont be surprised to find that he is the most hardworking person in the batch, and so we think he is crazy. A number of history legends fit into the shoes of this description, Isaac Newton, Bill Gates, you name them, look around and the list might overflow. These people are not crazy, they just know a little better than incubating in the comfort zone.
Comfort zone is literally that place of comfort, where everything is pretty much where it needs to be. We all love this zone, and our ultimate goal is probably to get comfortable. We pursue goals, when we succeed we get comfortable and when we fail we lower our expectations to get comfortable. The comfort zone is safe, its' warm, and cozy, which is not a bad thing in itself. We need that warm place to reenergise. The only downside to this zone is that it is marked by absolute zero life.
People measure success by how much they have, or appear to have. Successful people measure success by the rate at which they are moving. You don't need calculus to understand the difference between the two. What you have isn't good enough if it is currently depreciating or not growing at all. Stepping out of your comfort zone implies growing with every second, learning something new and facing each day with passion and enthusiasm. Assets and material rewards are important but what really counts is what happens subconsciously as you acquire those rewards.
A Chinese proverb goes, "a man grows most tired while standing still" further pointing that the comfort zone is comfortable, but not in any way fun. I have a simple algorithm that has pushed me to places I never imagined, pursue goals, if you succeed, move on to new challenges; funny thing is even when you don't succeed you'll have to do the same. Life is too dynamic to settle for anything. Point is keep moving, life is most amazing out of the comfort zone.
