Sort LEGO like a machine.
By hand.

Batches, not pieces.

Don't pick up one brick and choose between 50 bins. That's what burns you out in minutes. Run the whole pile through one question at a time. Each pass splits it into a few groups, then you repeat on each group.

Your brain handles 5, not 50. Deciding between 3-5 groups is effortless, and you do it for the whole pile at once.

Never a 50-way decision. A 5-way decision, 5 times.

Split on the most obvious thing first.

Your first pass splits the whole pile by size and kind: Huge (baseplates and big builds), Regular (your everyday bricks, plates, tiles and slopes), and Irregular (the odd stuff: Technic, minifig parts, plants and animals).

Every pass after that picks the one question that splits a group fastest with the least thinking. Keep each split to about five groups, and let every group get smaller and more alike until it's easy to finish.

And don't pluck pieces one at a time. Spread the pile out, then use your fingers to scoop what you want into its group and sweep the rest aside.

Scoop and slide. Don't pick with pride.

Stop sooner. Store cheap. Stay sorted.

Go only as deep as your building needs. For most builders, stop at shape, not color. Your eye finds a red 2×4 in a bin of 2×4s instantly; place it in an all-red bin and it turns invisible.

Don't buy a drawer system before you know your group sizes. Start cheap, ziplock bags in one bin, and upgrade only when something overflows. Then keep one inbox bin: new LEGO, torn-down builds, floor sweepings all land there, and you run the passes on the inbox alone when it fills.

Sorting isn't a project. It's a system with a small recurring cost.
