The most disappointing part of school is taking a 101 class and making a bunch of deductions based on what you learn, and then taking the 201 and learning that other people had the same ideas first.

I dunno, I kind of enjoyed that. What is more disappointing is when those people thought of similar ideas but then made a very inconvenient way to describe them the "convention", e.g the direction of electrical current or pi.

That's good, it means you're on the right track.

Nah its way worse when all of your ideas are wrong and in the complete opposite direction, better to think in the right direction and get confirmation that you are thinking correctly as you go
