How do I apply my sales methodology to each deal?

A methodology gives you a map, but every deal is its own terrain, and rigidly following the map into a ditch is its own kind of failure. You are past the beginner stage of learning the steps. Now you are learning the harder art of knowing when to bend them, and that unevenness is the sound of growth. The method is a servant, not a master. Its job is to make sure you do not forget the important questions, not to march every deal through the same gates regardless of what is in front of you. Flexibility comes from understanding why each step exists, so you can skip or reorder it on purpose rather than by accident. On your next deal, before you apply the playbook, ask one question: what is actually different about this one. Adjust the method to fit that, deliberately. Doing it on purpose, and noticing the result, is how the flexibility stops being uneven and starts being skill.
