Some things just are never done and from experience I know that that kind of work would not suit me very well. When I start something, I like to work on it as long as it's finished. No matter how long I've done that or what time is it. After I'm finished, I can move on.

I ques the answer if one is a workaholic could be found from these things: recognizing if you are working too much, admitting if you do, knowing when it's time to stop, actually stop working when you do work too much. Also being able to let go of the thought of working so that your brain can rest too. But of course things never are this simple.

The good news is that I love the work I do. But that is almost beside the point, isn’t it? The point is that the day should end at the end of the day.

My opinion is that if you or someone else is miserable due to the fact that you work long hours, then it's a problem. But if you work a lot and enjoy it and also you are able to rest when you don't work, I think that's not a problem then. But as you said, you are somewhat troubled with the fact that as you work so much, you don't have time to do other things that you would like to do.

But is it workaholic(ness)? You are just passionate about your work. Is it more about the fact that you are one of those people (like I am) who would love to do so many things in life that it just isn't possible to do everything? And that you also don't like to leave things hanging? But as work and life is what it is, you have to choose and you have chosen. So the tricky part is not getting guilty conscience after choosing.

My way of doing things is (whenever I can) to do that thing I started without thinking what time is it. I start doing it and finish it when it's done, not earlier. Because I don't want to loose my drive. And then off to the next task or rest if needed. But as I sometimes work long hours, I also have more days off and more vacation days than what I had when I was younger. Days when I do nothing work related. Because I know if I start, I can't and I don't want to stop.

So my advice is, do what you love, do it the way you do it best and stop having a guilty conscience about the stuff you didn't do or did differently that how you think it's supposed to do. :)
