All hobbies have a tremendous amount of measurable value to their owners.
All hobbies require talents which are supported by knowledge and skills. Our hobbies and interests are extensions of our personalities and our heart's desires.
We can entertain one hobby or we can have many hobbies at any given time. It is not unusual for a hobby to become a business.
There are short term, long term, and lifetime hobbies. My dance interest became my first business, and now my writing hobby is becoming my second business. Speaking from experience, anyone who is active in any form of arts and crafts will not lack the wherewith all to experience an entrepreneurial lifestyle.
If a business is not of interest to you, then the making of gifts and sharing with others is very rewarding.
Perhaps, you do not have arts and crafts abilities. That's okay too. There are many hobbies which require observation only.
Being a spectator for any type of event, sport, or performance is needed.
