The map is not the terrain
The Daily Drip
The map is not the terrain.
In other words, the plan you made for how you will navigate the landscape of a problem is not a perfect or accurate representation of what will happen.
The map doesn't contain weather conditions, setbacks, accidents, or any of the other fun things we experience in an adventure.
Life is the same.
Make the map. Plan as best you can.
Just remember that you'll be traversing the terrain and the uncertainties that come with it.
Have fun.
