Unreasonable stubbornness (like staying 8 hours straight doing the exact same thing because I know I can do it but I'm failing for various reasons).
Unexpectedly able to start something random, to make it more hazardous by playing head or tail and to not totally fail it by constantly improvising.
I am novice and couldn''t' compare to any expert, but I know a tiny bit animal tracks as well, and tracked a little bit lynx a few years ago, which was extremely entertaining!
