As a graduate student I was required to take a course on Operations Research. I decided I would study with someone who seemed to have it all figured out (since he was ruining the grading curve for all the other students). As we studied and discussed the various homework assignments it was immediately clear he had a deep understanding and fluency in the material, even though it was his first encounter with it. I asked him “How are you so good with math?” (I’ve always liked math). He replied: “Last summer I decided to relearn math from the beginning because I wasn’t happy with my understanding of it”. I asked “What did you start from? Calculs? Trigonometry? Heck, Geometry?” He said, “No, from the beginning”.
Ohhhh!
We’re always in a rush to get things done, to reach the next milestone. In our haste we leave gaps in our work, in our understanding. These missing gaps add up and compound over time, like debt with interest. Repayment will certainly cost time.
I still try to move fast, but I cut less corners.
