I have to say that this won't be a comprehensive list, but I do have a few things I'd like to share. Here goes:
1. If your socks get eaten by your shoes, but you don't want to stop to fix them because you are running quite smoothly and nicely and things just seem so right (other than the socks, of course), stop and fix them anyway. Blisters are terrible things when you've still got 4 miles to go!
2. When something is bothering you, say so. If you can't make yourself say so, don't let it bother you. Easier said than done, I assure you, but it is soooo worth the effort!
3. A time may come, perhaps, when you need something. I believe there are two options on this one. You can (a) figure it out, or (b) ask for help directly. So, if you cannot bring yourself to ask for help, you have the other option. If you cannot figure it out, really and truly, then by all means, ask. The worst thing that can happen is that the person you ask will say no. Not the end of the world. Bonus: both options are better than just staring at said person until they guess what it is that you need.
4. Just because a person can run marathons does not necessarily mean one is in shape. Things like pull-ups (even jumping ones), burpees, and deadlifts can bring tears to the eyes!
5. Root beer kombucha is gross.
Well, that is about the size of it. This may not mean anything to anyone else but me, but I am so okay with that!
