I've done MSF which is incidentally GREAT as general driver's training. I've also got a US Sailing Basic Keelboat cert somewhere. Sailing has also had a big impact on how I think - learning to deal with forces much greater than you is very worthwhile.

If you live near a ski area, pickup the cheaper weekday season pass and do night skiing twice a week until you can handle the black diamOnds with ease.

Apply this to everything you find.
