I'm single too... I don't see the relevance, though. You don't just have to like working. You have to actively decide against doing much of anything else. If you are working ten hours a day with no weekend, or 14 hours a day with one, you're going to be exhausted for the rest of that time. You can fit working out in there (~30-60 min a day, plus travel time if you don't have your own equipment) if you're willing to burn the candle at both ends like that. At that point you will have committed the overwhelming majority of your time, and if you try to add anything else to your life, any kind of unexpected outing or emergency, or even just waking up one day and not feeling up for it, will have to come directly out of the time you've budgeted for your work and health.
