Saying it's outside of your control isn't entirely true. However, I do get not everyone can get to the center of that diagram; for some people it is within their control and for some it is not. To blindly dismiss it as a lack of control is a form of learned helplessness, however small, which for many is a root that creates depression. If you're depressed, this may be something you want to talk to a therapist about.
The question, then, is how do you balance: 1) making enough money for food and shelter with 2) your intrinsic values? Also, will making more than enough money help you further achieve your values?
The diagram presents a framework to find an optimal solution. "That which you love" is a function of your intrinsic values. The other 3 circles will help you efficiently convert your time into money to support what you love. I guess the better diagram would somehow convey the fact that, ultimately, what really matters is that which you love.
