Invest most of your time in the most valuable domains where you are distinctly great.

If you are merely very good, you're a part of the pack and you have to fight to keep on top and be noticed.

If you're distinctly great, you stand out prominent from the pack, obviously in a league of your own.

Invest the time in the games that are most valuable, otherwise you end up in little micro-niches that no one else cares about.

If you aren't yet distinctly great, invest the time in the domains where you might plausibly become not just very good but great.

Sometimes that's not "the game you're already very good at" but "the game you just started on but are already surprisingly great at" or "the game where your skill is improving most quickly with the highest implied ceiling."

The derivative is more important than the value: how fast you're growing.

This is a recipe for seeking out and staying in your flow state, your highest and best use.
