Is the 'Digital Nomad' Lifestyle Everyone's Talking About Actually Possible?

I've been seeing a lot about the digital nomad lifestyle on social media lately, and I'm curious if it's actually feasible. I work remotely, so I'm considering trying it out for about a month in Southeast Asia. But I'm worried about time zone differences, internet connectivity, and the challenge of balancing work with sightseeing. Is there anyone here who has actually lived as a digital nomad? Could you share the pros and cons, and what I need to prepare?
