Jeff,
You can call me biased, but I would recommend to you to keep track of your lifelist on http://www.elifelist.com. It is a social site where you can create your own list with some inspiration from browsing other people’s lists and manage it with pictures, videos, and stories as you complete each item from your list. Lee Briggs and I created the site and are currently in the process of checking an item off of both of lists, bicycling across the country. We are in Nevada now and after starting in North Carolina, only have a few days of biking left until we complete our journay.

Good luck on completing your PhD and paying off all that debt.
