If you mean breaks by breaks from my routine. It’s quite difficult for me to exercise everyday since I can’t drive but I do exercise 5 days a week so I guess that counts as a 2 day break. Usually I don’t stir away from my routine as it benefits my outlook on the day ahead of me. Unless you have a good reason to take a break I wouldn’t. Bottom line I don’t take breaks often.
It depends. If I work for a small amount of time I work without pausing for 1h or 2h. If I have a longer day planned I pause for 10 min every 50 min
