Zealets vs Day Dreamers
One can want to do something meaningful because of a dream; The reasons and goals may be righteous. One can not often do a complicated thing well with dreams alone; Planning, stability, and flexibility are all required. To fix a problem during your lifetime may be a great achievement. To have a problem stay fixed after you are gone because of a well-thought out and sustainable plan should always be the goal.
Emotions are great motivators but terrible co-pilots.
