Key takeaway

Sales is not one skill. It is seven discrete sub-skills you can isolate, practice solo for a week, and self-grade. Most beginners try to improve everything at once and improve nothing.

Key takeaway

Each of the seven sub-skills has a single failure mode that accounts for most beginner mistakes. Naming the failure mode in advance is half the practice.

Key takeaway

The skill almost nobody practices on purpose is the honest no. It is the highest-compounding skill in this list.
