It is a gift that you are able to find something you enjoy in those extra long commute hours.
A realtor friend of mine used to work as a fulltime flight attendant, at the same time, worked as a real estate agent, not only that she also mothered 6 children (ages from 6 to 20), and homeschooled the younger ones. For the past 7 years I have known her, she did not seem to age a bit, amazingly.
Just a little story to add some fuel here, inspired by your self-rising high spirit.
