Why Teaching Underperforming Adults Fails and How Hiring the Right People Cuts Management Pain

1. Adults' mindset is hard to change

The author recounts a colleague who, after six months, showed a good attitude and never complained but never took initiative. When a project stalled, the colleague waited for explicit instructions instead of proactively solving problems. Various attempts—one‑on‑one talks, templates, weekly reviews—only temporarily improved behavior before reverting. The author concludes that an adult's thinking style, sense of responsibility, and work standards are largely fixed, making external attempts to reshape them nearly impossible.

2. "Wait‑rely‑ask" is inertia, not attitude

Initially the author blamed himself for not teaching well, but after leading more teams he observed that people who habitually "wait‑rely‑ask" do not see the need to proactively identify issues. Training can teach methods, but cannot instill the habit of asking questions. Even after ten repetitions of a method, the person returns to the same passive behavior. This inertia stems from decades of personal habits, and a single meeting often illustrates it: the person claims there are no questions, then returns minutes later to ask for clarification, showing a lack of questioning habit.

3. Hiring decisions set the foundation of management

The author shifts focus from "how to coach" to "how to select people". A wrong hire at the employee level can be dismissed, but a wrong partner is harder to remove. Many management problems appear as "I can't lead this team" but actually originate from hiring the wrong person initially. The principle is clear: you can only lead the right people effectively.

4. Say "no" early when the fit is wrong

If you find yourself hesitating to decide whether to keep someone, the answer is usually already evident. Delaying the decision costs the most: another three months may be wasted, projects delayed, team morale drained, and ultimately both sides suffer a prolonged separation. Promptly saying "no" protects the manager from further loss and gives the mismatched employee a chance to find a more suitable role.

5. Final thoughts

The biggest pitfall the author faced was not poor coaching but hiring the wrong person from the start. Adults are difficult to change; instead of banking on slow teaching, invest effort in rigorous selection before onboarding. Choosing the right people can halve management difficulty, a lesson that becomes easier and more cost‑effective the earlier it is understood.
