Flexible work hours
With a physical workplace, and commuting, work hours are standardized. Now, my work hours are divided into two blocks, one block in the evening after kids are asleep. This allows me to be more flexible when it comes to collaboration with different time zones.
Starting collaborations with people far away is now less of a mental hurdle (this last month, I have discussed research with people from at least 5 different countries on three different continents).
