Imprecision
Let’s me frank about something, and no, that’s not my name. Not everything requires precision. If you asked about how many years I dedicated to my education, I will go with a very round estimate.
There are several reasons for that. I didn’t always pay attention. I did change my discipline, a few times. And I learned that precision is not important when trying to decide how many years. I learned that one detail, and it may be the most important one.
I’m still busy learning, but I now realize that you can draw conclusions that will later need corrections. Thank you, every math teacher along the way. I also learned that grammar is important, but only up to a point. The idea of “free translation” is important. Thank you to my various language teachers. I also realize that the ability to climb a rope suspended from the gym ceiling is important only while climbing. Everywhere else, they put in stairs. Or a ramp. No help ropes, anywhere else.
I guess the real point, as I spend my spare time trying to understand material that is unfamiliar is that I have time to go back and review, until I don’t do too bad; it took me so long to clue in that. Yes, even the tax people allow math errors. And do-overs. Not too many. Use a pencil for the rough copies. Also, when reading a timetable, arrive early. The people that run transportation systems have poorly developed senses of humour. Running after that train, boat, plane looks silly to everyone else.
