There are Two Strategies for Learning Something

• Depth-first. This is where we pick one area and drill down.
• Breadth-first works by first exploring your surroundings. If that doesn't work, pick one direction and fan out again.

If the area you're exploring is bounded or set out, like a syllabus, both strategies will work. If learning is without bounds, going in-depth first may lead you on a long detour. Choose poorly, and you can get stuck on an unwanted path.
