I had a similar confidence boost when I developed a Vulkan graphics engine. People talk about this library or that framework being hard to learn and use, but when you have struggled through Vulkan and 3d engine quirks, some of them seem like a walk in a park now.

So to answer the original question, my epiphany is that something being "hard" is a relative thing and that "hardness" should never be a barrier that keeps me from reaching my goals.
