I remember a PG tweet along the lines of "if faced with a choice between two things, pick the harder one".
But when picking a strategic goal, like a startup product, building a moat is advantageous.
I did Mathematics instead of CS before switching to CS. The maths in the latter was so easy in comparison. I should have always done the latter. I would have been where I am much sooner with a lot less heartache. There’s no moat with this degree. Other people find Algebra far easier than I did. It is pointless to go play where you don’t have home advantage.
And also, ultimately, the heuristic is good but heuristics aren’t always correct. That’s why they’re heuristics but not laws. I believe this is a heuristic.
