Theoretically you could list your skills here and how often you've used them (if you wanted to convince a mod you could use an update) but remember that your automatic charactersheet does a pretty good job of keeping them up to date.
Periodically you could ask yourself questions like:
- In what way has my character matured?
- What key events have influenced my character and how? Are there any changes to list?
- What has gone well for my character? What has not gone well for my character?
- What aspects of my characters personality have surfaced? Which aspects would I like to explore further?
- Is your character part of a group or alliance? Is there anybody whom he favours or looks up to?
- What has your character told you that you didn't know before? What hasn't he told you yet?
