A common mistake for new managers is to do their reps' jobs for them, especially in tough deals. This approach, born from insecurity or a desire to prove worth, prevents the team from developing self-sufficiency and ultimately fails to scale. The manager's true job is to build skills and muscle in their reps.

Promoting top individual contributors into management often backfires. Their competitive nature, which drove individual success, makes it hard to share tips, empathize with struggling team members, or handle interpersonal issues, turning a perceived win-win into a lose-lose situation.

Leaders often expect reps to drive one-on-ones, but the best leaders prepare beforehand with a clear point of view and desired outcomes, treating their reps like internal customers who deserve preparation.

A sales leader's job isn't to ask their team how to sell more; it's to find the answers themselves by joining sales calls. Leaders must directly hear customer objections and see reps' mistakes to understand what's really happening. The burden of finding the solution is on the leader.

First-time managers, often former top performers, default to doing the work for their reps. This creates dependency and prevents the team from developing self-sufficiency, which is crucial for scaling. A manager's true role is to build the team's skills, even if it's slower in the short term.

Ineffective leaders use Quarterly Business Reviews to demonstrate their power by grilling reps. Great leaders use a single deal review as a live coaching session for the entire sales floor, knowing one person's mistake is likely a problem for hundreds of others.

A sales leader's value isn't in managing from headquarters. It's in being on the front lines, personally engaging in the most challenging deals to figure out the winning sales motion. Only after living in the field and closing landmark deals can they effectively build a playbook and teach the team.

Effective sales leadership isn't about managing spreadsheets; it's about leading from the front with deep product knowledge. A leader who can't sell the product themselves cannot effectively judge their team, determine what "good" looks like, or have confidence in their forecast.

Many leaders mistakenly manage their team as a single entity, delivering one-size-fits-all messages in team meetings. This fails because each person is unique. True connection and performance improvement begin by understanding and connecting with each salesperson on a one-on-one basis first.
