I am always striving to learn more and develop as a person.  Here are some of the sites that I have found useful in that process

Myers-Brigg - Understanding more about yourself and what motivates you to do things (I'm an ENFP - the Inspirer or Champion (!).  Having said that, I would agree with everything they say I'm supposed to be, not sure about the Champion bit though!

Five Rituals - This is a book that shows techniques for maintaining youth!  Always a good one to know

Triathlon Training - One day I will compete in a mini-triathlon.  It was supposed to be this year, but setting up our business has taken up too much time, but I will do it!
