Rappelling down a three-story wall!

My friend Dave got tickets to a rappelling class over the weekend. It may not have much to do with what I normally write about, but I can’t help sharing some pictures.

I recommend the activity to anyone. It’s easier than you expect and fun. I did it in Brooklyn with Hollywood Stunts. They were professional and fun, so I recommend them.


The light was low so not many pictures came out. Some pictures are of Dave at the top.


Longtime readers will recognize Dave as the guy I swam across the Hudson River with. Recent viewers will recognize my shoes from my marathon pictures.

I read a lot of leadership, professional development, and personal development books. Almost all tell people principles instead of how to learn things themselves. Principles sound[…] Keep reading →
