In video games it's common for characters to run by default: it's faster, why wouldn't you? I think this is also a good approach to apply in real life, at least over short distances. It saves you time and it's a bit of exercise. Over pretty much any distance short enough that I'm not going to break a sweat I'll run.
I've done some of this most of my life (I can still hear my middle school principal shouting to stop running in the hallway—Jeeeeff-reeeey!) though over the last five years or so I've pushed myself to do it more consistently. The more I do it the easier it gets, and the shorter commutes become.
Note that this is another example of describing something I do that works for me, and that I expect would likely work for many more people than I see applying it. But probably not more than 30% of people, though?
(Prompted by a coworker talking about the inconvenience of an 8min distance between two buildings at work that I think of as a 2-3min distance.)
Wild, thanks!
