How coincidental! I used to give guitar lessons a while back. With currently being fully immersed in farming, we don't have time to spare. What's often in our minds is the next farming project we can start. Farming can be hectic but equally rewarding as well.
I don't work anywhere else, either. My wife likes to sew, so she makes different crafty things to sell on Etsy. It doesn't bring in a lot of extra income, but it does help us out.
