I've felt embarrassed if my shoes became untied, its just kind of unbecoming. Ever tie your shoes and the damn knot goes sideways, with the loops coming from the top and bottom? Well here's the cure to all of your knot compulsions.
Notice just below the instructions on TFA:
NOTE: If your finished knot comes out crooked, it's probably because you tie your Starting Knot the opposite way to mine. This will result in an un-balanced “Granny Knot”, which both sits crooked and comes undone more easily. See my Granny Knot page for more information.
The Ian Knot is great because the knot works properly wrt how the strings pull against each other. He also explains how and why to have loops and strings come out the sides perfectly, and with the knot round shoe laces like on dress shoes, leather laces, work boots, whatever will basically never come undone.Good knot, and really easy. It'll take you about 15 minutes to master, an hour or so if you have poor dexterity.
Also the psychological benefits of doing something well.
But now I'm also keeping an eye out for over-optimizing.
