The 20-Minute Struggle Timer

The stuck minutes before a solution are where logic forms. This timer makes them survivable: open any problem, hit start, get the right move for every phase of stuck.

The 20 minutes you spend stuck before looking at a solution is where logic is formed. Skip it, and you're buying answers instead of building skill. This timer makes the stuck time survivable: open any problem anywhere, hit start, and it hands you the right thinking move for every phase of being stuck.

No code yet. Restate the problem in your own words. Write the inputs, outputs, constraints, and one weird edge case. Can't restate it? You haven't read it.

Open any problem anywhere, then hit start. No hints, no solution tab, no quick peek till 00:00.

Why 20 minutes? Why not just watch the solution?

Because watching is smooth, and smooth means nothing is being built. Struggle first, and your brain creates the exact hooks the explanation will hang on. When you finally see the solution, it sticks for good instead of evaporating by next week. The struggle isn't the price of learning. It is the learning.
