A very interesting point of view. That’s funny that I live by those very same principle even though I grew up with a completely different background.

However, there is a thought that keeps rolling in my head, I think your spoke theory lacks a quite important statement. You have a fixed amount of time available in your day and in your life. Working on your body or mind, you can increase your stamina so your personal wheel is somehow expanding. You end up with more energy to spend with your family, even after an exhausting day of work. But still, you have a fixed amount of daily time. All that energy is kind of useless if you don’t dedicate time to people / project / work / sport. In a sense, there are boundaries until which you cannot “evolve” and those limits are somehow related to time.

I don’t really like the idea to live with the thought that we are all going to die some day, it feels like you constantly have a Damocles' sword upon your head. Too much thinking about that and you tend to burn too fast. Not thinking about that and you don’t feel any emergency to do the things that could fulfill your life. There should be a way to find a balance with this notion as well.

Maybe it could be the axle of your wheel that supports a certain amount of weight.
