Never underestimate how much you can learn by taking one area of interest and seriously leaning into it with all your might.

After enough reps, it branches out. The higher you climb up the skill tree, the more it intertwines with other skill trees.

You thought you only cared about one thing, then suddenly you need a hundred subfields of a dozen other domains to keep climbing.

So just pick something and lean in hard. However far you think the road goes, it goes further. Depth is where the interesting doors appear.
