It never ceases to amaze me that you can be stuck on a problem for 2 days, say “screw it I’m going for a walk around town” and then solve it fifteen minutes into the walk.
@christianselig Funny how everybody seems to be experiencing the same phenomenon. And I always thought it was just me...
But no matter how often this works: Next time I will try to stay awake to solve the problem again. And again. And again.
