In fact,I think your life really not bad,simple,happy.The most important thing is that you not only have plentys of time to do what you want do,but have a good salary as well.At the beginning,according to you passage ,I have thought this kind of mid-night job requires to be done every day and have an ordinary salary.After that,to my surprise,it is a good job for the people who can not find a properiate job at first.I am learning English for immigrant now.If I can immigrate to Canada,thinking from my position,I probably will work on this sort of job.Anyway,very thanks for your taking time to provide so many information for us to share with.You have a very nice family.With my best regards!
