People are very different. My gf cannot sit down and work for more than an hour before she needs to go for a walk and take breaks. In general, she doesn’t find office/computer work fulfilling and is looking for a more dynamic career.

I on the other hand can go 12 hours getting up once or twice to go to WC and will skip lunch. Taking a break most of the time sounds like a punishment. When I’m working on a problem and hold a lot of information in my working memory taking a break would only set me way back. Meetings are avoided unless absolutely necessary. Emails and messages are answered before I shut down as they don’t require much focus. That’s how I love working. But I’m also very introverted and robotic. I need to find a more balanced approach and appreciate my gf’s influence on me but it doesn’t come naturally to me.
