If you can say your idea in one sentence, you can build anything on top of it.

A single clear sentence is a test of whether you actually know what you are making. When an idea needs three minutes of setup, the vagueness spreads into every later decision. Compression forces you to decide what the thing is for. Once that is settled, the rest of the choices get easier, not harder.

Write your current project down in one sentence without any ands. If you cannot, that is the real task for this week. Keep rewriting it until a friend could repeat it back to you correctly.
