How do I trust my own judgment instead of just the rules?

Leaning entirely on the guidelines because your own judgment scares you is understandable. The rules feel safe. If you follow them and something goes wrong, it is not on you. But judgment is part of your work, and avoiding it holds you back more than any single mistake would. Judgment grows only by being used. Start small, on lower-stakes cases, and check your calls against what actually happens. Over time you build a record that shows your instincts are sounder than you feared. The guidelines become a floor you stand on, not a wall you hide behind. On your next borderline case, decide what you think before you check the rulebook. Then compare. That small habit is how trust in your own judgment is built.
