When I started off, I used to enjoy all programming regardless of whom I did it for. Now, 20 years later, I enjoy only the programming that I do for my own ideas/projects/business, and don't enjoy the programming I sometimes have to do for others. Another aspect that impacts the enjoyment for me is the part of the architecture I'm programming. I enjoy everything server-side or analytics related, especially if it's in Python / Java / C++. But I don't enjoy front-end activities like HTML/CSS web designs, javascript, or android front-end. I find front-end coding frustrating because doing it well sucks up too much time for little value and not much learning I can use in future, but cutting corners is also not an option because it's glaringly obvious and off-putting to users. So it's a mixed bag. In my case, I'd say I enjoy 80 percent of all the programming I do.
