A few years ago this article appeared in a D.C. newspaper. I thought it was a pretty good perspective on the 'value' of hobbies in our lives.....the NON-financial aspects, if you will.
Career Coach: The value of hobbies
By Joyce E. A. Russell May 5, 2013
Recently I asked an executive I was coaching, “What hobbies do you have?” He paused, looked at me blankly, and then replied, “Actually, I don’t really have any,” followed by another long pause. As he reflected on this, it seemed to suddenly strike him that his life was way out of balance. He was living and breathing his work, which was his own company. The little free time he had, outside of his business, was spent driving his kids to their various activities and watching them play sports and take music lessons. While he loved spending time with his kids, he felt that something was missing in his life. He also reported that he often felt tense, stressed and was increasingly having difficulty controlling his temper.
Many of us can relate to this lifestyle. We have long given up on having any personal time in order to devote our energies to our work or families. But rarely do we give ourselves time for our own activities. Yet finding time for ourselves is key to our own sanity. It can actually improve all the other aspects of our lives. Having a hobby may be even more important to people who lead very full and busy lives.
Defining a hobby. The Merriam-Webster dictionary defines a hobby as a pursuit outside of one’s regular occupation, engaged in especially for relaxation. It’s not something you “have to do,” but rather something you “want to do”— because you love to do it. As a result, a hobby can take many forms, be it stamp collecting, gardening, woodworking, playing tennis or even traveling.
Research has shown that people who have hobbies are generally healthier, and have a lower risk of depression and dementia. Many executives that I have coached say a sport or physical fitness routine as a hobby keeps their blood pressure down, enables them to manage their anger and daily frustrations, and puts them in a much better frame of mind. Consequently, this impacts their quality of life, work and family time. Michael Brickey, author of “Defy Aging,” says that an ideal hobby would be one that serves three purposes: a diversion (escape from daily life), a passion (engage in something you love) and a creation of a sense of purpose.
Benefits. Scheduling time for a hobby in our lives (tennis league every Monday night or a weekend bridge tournament) enables us to take a break with “permission.” Since we have signed up, we feel we should show up and we are “forced” to take a break. Some people need to structure their hobbies into their daily lives, otherwise they would feel too guilty to take a break from work. Many hobbies also provide a social outlet for us if we join teams or interact with others (a sewing group, a chorus). These social interactions can provide a degree of social support we may need. Hobbies can also bring pleasure to our life. I have talked to many executives who reported the sheer joy they got from traveling to new places or taking a cooking class. Hobbies provide an outlet from daily stressors that can keep us from getting burned out in our jobs. They also provide numerous health benefits from lower blood pressure, to better physical function, and higher positive psychological states, and less memory loss. Further, hobbies may actually improve our work performance if they improve our decision-making skills, creativity and confidence.
Finding time. Setting a routine to carve out time is important initially. You may have to give up watching TV every night, or you may have to force yourself to leave the office a little earlier each day. Make your hobby a priority. Set goals for yourself and get a buddy to support you and to help you stay with a hobby.
“All work and no play makes Jack a dull boy” is a famous proverb. There may be some truth to this so make sure you find some time for yourself to relax, enjoy some fun and pick up a hobby — especially if you are depressed, stressed or going through a tough time. You will thank yourself for it, and so will your family and colleagues.

I've been working behind the counter at our local hobby shop for about 18 years since retiring from a corporation. This issue of the hobby's "value"....wherein "Value"= Financial Return...has always amused me. Every time I talk with my financial adviser I never seem to be encouraged to explore the world of ...."Hobbies"...when it comes to my 'balanced portfolio'. Hmmmmmm.....I wonder why? 
And, yet, back in the days of the first releases in the Joshua Lionel Cowen series of engines....the ones in the black boxes...there was this natilly dressed customer who came through the door. None of us had seen him before.
He was most interested in the JLC series of engines just announced. He expressed a strong determination to pre-order one. But 'Which one?', was his dilemma. We talked. He asked a lot of questions, most of which seemed rather strange for someone actually in the O3R hobby. After about half an hour he asked me the '$64,000 Question': "Which of these engines do YOU think will increase in value the most in the future?" I said, 'None of them, probably.' To which he left. Never have seen him since.
Value of this hobby, or any item thereof?....fun, enjoyment, escape, relaxation, friendships, et al.
Period.
Just MHO, mind you.

They still have a few years of premium prices left in them until Lionel introduces something that REALLY obsoletes them, and I just don't see that happening anytime soon. Time to take that poker hand elsewhere. 
Just another one of life's little ironies I guess.
