Personal timeline

I need to create one of these to track moments of inner awakening and moments of significance that have led to personal transformation. They usually occur in some subtle way, but I'd like to commemorate them somehow, and also track my progress to see what I've been accomplishing.

There is some software I need to download. In the meantime, what should I put on this timeline? I'll have to start brainstorming some ideas, possibly using my freemind software. Or maybe I can use my freemind software for the personal timeline?

I like that idea actually . . .
