The simplest one is "Happy, Meh, Sad + Action Items" (The one I told you about yesterday) On a piece of paper, make the 4 columns, and for 10 minutes just write down what went well (Happy), what was so-so (Meh) and what isn't going well (Sad). Then, go through the lists and think out loud what you can do to improve on it. Usually, that's for the "Sad" column items.
