Everywhere you turn there are things that could be improved, fixed, wrongs righted, dictators toppled, famine, poverty, racism, sexism, classism, problems that need solving, things to be understood, things to be simplified; things that make everyone's lives safer, more bearable, more comfortable, happier.
If you take a hard look at the world around you and look at ways to apply what you enjoy doing to making people's lives around you better, your passion will come alive.
Why seek to control anything? Why not exploit it to make everyone's lives better?
For example, seeing your neighbor's abandoned, dilapidated house as a chance to start a farm or garden, is not something most people would think of when viewing the housing situation in Detroit. Grace Lee Boggs saw it that way but most do not.
The thing about control is about letting go of perfectionism. If you have an inclination to improve things, you can be overwhelmed by the number of things which could be improved, and it can be demoralizing to see the breadth of it all, and recognizing how little overall impact you, as one person, can have. So you limit your scope. You can't do it all.
