The boys are going to be very proud of their Dad when he's all done! It's good for them to see, because they see that to succeed in life you need to be willing to work hard at it.
Absolutely! My dad set me that example early on... also taught me the importance of getting a good education and doing what you love. Mom worked hard too but Dad's job seemed more glamorous at the time. Of course know that I know what's involved I think Mom may have gotten the better deal after all.
But Dad has cooler hobbies.
