I try to invent a new way of thinking or doing something every day. Why do I do this?

 At any time in life but especially as you get older unless you are very adaptable you are soon gone.  For me, this wasn't ever a problem. For me, the problem is Empty nest Syndrome where your kids all move away to other states or countries. This is my problem.

But, "There are no problems only opportunities" so I go visit my kids or pay for their airline tickets to visit me and my wife instead.

So, to me, retirement is an amazing opportunity to research and discover new things and to travel new places. If it is not that often people are gone within about 5 years from either overeating, Drugs or alcoholism. I have watched this all my life.

At least people eat better and job or exercise more now than they did in the 1950s and 1960s where people died like flies everywhere in the U.S. often by ages 35 to 55 years old, especially in the building trades where I grew up in working with my father.

Often people cannot safely keep up the rigors of the building trades after 40 unless they are the contractors hiring people who do all the bidding and don't work hard as much anymore. So, there is this range between about 15 and 45 or 50 where people can keep up that workaday tradesman pace ongoing without having too many physical problems or mental problems to keep doing this every day during the week.

So, a part of my philosophy has always been "Work Smarter not Harder". However, it is also true that all the men in my family that survived world war II had their own businesses too which is a whole different way of thinking than working for someone else. IN fact, when I researched my father's line all the way back to about 1580 in Switzerland men tended to have 5 to 10 kids and own their own businesses in both Switzerland and the U.S. after they came here around 1720 or so to Philadelphia for Religious freedom.

Philadelphia was originally where people went from Europe for religious freedom here in the U.S. especially in the 1700s.
