Notes are a tax on attention. Every line you type during a conversation is a moment you are not actually in it. Then the follow up sits on your to do list for a day, the details fade, and the momentum cools.
The habit that works is the opposite. Take no notes. Be fully present. Then capture a short, honest recap the moment you hang up, while it is all still fresh. What was discussed, what matters, and the one next step everyone agreed to.
Two minutes of that, shared right away, does more than an afternoon of cleanup later. The other person feels heard, the next step is clear, and nothing slips.
Wingman writes that recap for you as the call happens, so you can keep the no notes habit and still send the clean summary before you stand up.
