Just four days a week and a year. That is a far cry from "a pleasure cruise to the moon" and "peace for all mankind".
But there is a middle ground. You can certainly work towards things, but depending on your situation and available resources, you may not be able to achieve some of them in the desired time frames.
If a four-day week was important enough for you to literally kill for - and yeah, that's hyperbole - you could probably find a way of making it happen if it was more important to you than to everyone else.
