This is precisely why one significant mistake students sometimes make in learning math and science is jumping into the water before they learn to swim.11 In other words, they blindly start working on homework without reading the textbook, attending lectures, viewing online lessons, or speaking with someone knowledgeable. This is a recipe for sinking. It’s like randomly allowing a thought to pop off in the focused-mode pinball machine without paying any real attention to where the solution truly lies.
