One does not simply succeed in combining work and travel if they travel in the same way as before. What you really need, in addition to proper planning, are longer stays. If you go for a 10-days trip, just trust me, you’ll be productive for at most 6. But if you take three weeks, losing four days in total to deal with settlement, post-flight fatigue and finding your spot, won’t really feel as bad. It shouldn’t feel like “I’m on a vacation and I also work”, it should be more like “I work, but the view is nicer”.
