The first time

The 7 1/2 Lifelong learning habits were interesting. Most seemed self-evident. Easiest for me was taking responsibility for my own learning. If I'm not self-motivated then I'm not going to get anywhere. Problems are definitely challenges - usually interesting ones. Running into stumbling blocks, especially when I'm researching history, leads to fascinating discoveries.
The hardest part of those 7 1/2 Habits was the part about setting up a Learning Contract. That seems too much like work. If I'm going to study something I make the decisions about the parameters of the study and then go at it. Codifing it is too tedious.
