Substrate

Apparently MTA (the company running the NYC subway) has a real-time API. My fascination for the subway takes autistic proportions and so obviously I had to analyze some of the data.

I became well-rehearsed in failed attempts, and so much more patient as a result. ​ As a result, my tolerance for frustration is so much higher. I’m convinced that the seeds of patience and resilience were planted and sprouted in those math notebooks. ​ The art lies in knowing which tool to grab ​ And just because I arrived at an answer, didn’t immediately make it the right one. ​ Answering that question directly is a mistake. When are you going to need to factor a polynomial in the “real world”? Maybe never, kid. Especially not with that attitude. But when are you going to face a problem that requires focusing for more than 30 seconds? All the goddamn time. ​ I needed that bottom row of math textbooks. They were my anchor. The bedrock. The foundation for much of what I’ve learned, and a sturdy base for everything still to come. ​ At times, I hated math. And yet, six years later, I’m so grateful that I studied it. The reasons have nothing to do with numbers and everything to do with life.
