On a different note. I have been really fortunate to integrate my endless hobbies with work... astronomy, photography, exploring the world... mountain climbing. Along the way I was able to take off over four years in one year increments in between jobs to bike ride cross country, back pack, explore...etc.
Some smart person mentioned to me that it takes five years to get accustomed to retirement. How big a change it is, depends on the person. I felt a little skeptical.
So, for me. My endless pursuits instantly filled all my time. However, I did notice the lack of the goal. All of our lives are in pursuit of a goal... first grade... high school, college, first job, promotions, financial security, great vacations... they are always there. Then they are not.
So I did notice that I continued discipline in aggressively managing my investments, planning trips, etc. There was that drive to pursue... but it seemed strange... that this time getting to the end was no longer the point... So, over time I relaxed (music very helpful). My focuses changed to learning... history, philosophy art... etc. So, over time the focus became my true interests... and not the artificial ones that work provide. So, I am completely interest driven in a relaxed fashion. Yeah, it took five years to relax and really embrace retirement. Kind of like breaking in a pair of leather shoes... there is adjustment to become perfect.
