One directional thinking
(this is a play on the phrase one dimensional thinking)
Focus on one clear idea and follow it step by step to a simple conclusion.
Keep your attention on that single path, and avoid distractions or unrelated thoughts. Allow each sentence to build on the last so that your thinking stays clear, direct, and easy to understand.
Trust yourself as you move through this process and believe in your own judgment because confidence in your own thinking allows you to stay steady and focused.
