What a great thread. Some of the things mentioned above are the same I will be doing going forward, however if there is one thing that sticks out the most is to spend more time in one place to enjoy and appreciate that city / country etc. I used to love to squeeze in a number of countries in a given trip to try and "maximise" as much possible and rush from one place to the other. Being stuck in lock down has given me a sense of perspective that sometimes less is more.
Not saying this will last forever but for the next few trips will take the time to enjoy the destination
