Take a moment to look back on the events that happened. What did you see, hear, think, and feel? What did it do to you? You can just write this down or use a Simple Empathy Map to note down your observations and reflections.
E.g. I notice I feel unprepared for meetings. I am not sure about what we agreed on to do before every meeting. I feel I am missing things and I feel others feel I am missing things as well.
The next step is about abstracting your observations and reflections: what general insights can you get from your reflections? What are returning elements that you can re-use on a structural basis?
E.g. I guess I need to prepare better for meetings. Maybe I should find a way to take some time at the end of the day to see if I processed all notes I made in the meetings.
The third step is about implementing these insights into your daily practice.
E.g. You could create a 1:1 meeting template on your own. You could carve out 30 minutes at the end of each day to reflect on all your meetings. You could sit down and fill out a meeting canvas to take it even further and make structural changes to how you attend and run meetings.
The final step is about actually doing it. And keep doing it to make it a part of your daily habits. I have a separate category on habit forming.
