Some people do enjoy their work and can be said to live for it. Marissa Mayer had an interesting take that burnout wasn't necessarily about working too much but resentment that they'd rather be spending more time on something else (like family). To paraphrase a similar view someone once told me: there's no such thing as work/life balance, it's all just life. That being said I think it's easier to live to work if you feel that your efforts are going to yield greater results. Putting time into study to get good grades and learn new skills, anticipating that this will yield better job opportunities? Sure! Working long hours on my startup that is taking off and could make me rich? Great! Having to work long hours and skip vacations to finish a project in a salaried corporate job? That'll burn you out because you're not directly benefitting from the sacrifice, which probably leads to some resentment towards your employer.
