Taking trainings with colleagues can be fun.
A lot of times we "write the story" before we have all the information from the other person. It's very easy to read false tone into texts and emails.
Working through a parent pick up for 300 children after an event. Didn't take into account the length of time it would like for a "car rider line" switched gears and took a totally different approach.
I have not had this experience, but giving an agenda with specific time slots is a great way to keep on track and giving people to ask additional questions later after the meeting.
I'm thinking of a leader in the church successfully raising money for a building fund. Open, honest casting vision for the future and explaining exactly where the money will go and giving personal testimonies.
