I've decided to work on getting rid of a trivial useless habit: pushing pedestrian crossing buttons more than once.

Now, there's an argument that it's not completely worthless to do so: the typical button has no feedback whatsoever that it's recognized my push, so if it is at all unreliable then an extra push reduces the chances of a complete extra cycle wait at little cost to me since I have nothing else to do.

But the failure case has never actually happened in recent history, so I'm spending too much time pushing buttons.

So far I have remembered to push only once out of about ten times (2-3 per day). Of course, I immediately remember this resolution right after pushing twice.
