You can plan, work your plan, execute your plan and hope it all works as you hoped. Of course having some help along the way can make that plan come together. If you don’t plan then you have to hope for the best. Planning is smart but you can have some improvisation along the way to adjust for forces outside your control.
When you are so tired that the most mundane thing makes you giggle uncontrollably and you fail to make a whole lot of sense. That is me on this Saturday night. Man I need so much sleep.
