Do not, however, make the mistake of expecting that simply because you made a plan, it will go as expected. That’s an exercise in futility.
It’s much smarter to assume that your plan will only go perfectly until you start it. After that, as they say, “Life is what happens while you’re making other plans.”
When things get tough, keep your head down and your eyes on the prize. (OK, that’s a mixed metaphor which technically would only make sense if your goal was to look at your shoes – but you get the point.)
