Working on the dividend income with the aim to eventually leave my current field for another more enjoyable one that'll likely pass less. The dividend income will supplement the difference if necessary until hopefully I can completely stop working and do whatever I damn well please. 
I wouldn't mind a second job. I had a couple of possibilities over the past four years but they fell through. They both were ideal as they wouldn't have impacted the primary job at all. Ah well. If I had either of those jobs or any future second job I would have used the income to pay down the mortgage even faster.
There is the possibility of rental income in the future if the mother-in-law buys a place here for us to live in and then our current place can be rented out.
