People say they need to get a work that is tightly coupled with their hobby and I often disagree with that. Yes there are examples of people who do things that they love and get their bills paid, but that is not the majority. The majority works to pay their bills and often think they like to do something else.
But it is fine, what is your problem if you can do something for 8 hours of your day, pay your bills and get the remaining 16 hours of the day to do what you love. Do you really have a problem with what you do for 8 hours? Loving your job has a lot to do with you and there is never a dearth of things you can crib about.
But hey, you have a job and you are contributing value.
