We don't have to be a teenager - I think I still have the "beginner's mind" since I've only been riding less than about five years. I'll just hop on an go, might be wearing anything, might go any distance. The only difference in attitude from the beginning is that I now have sense enough to stop before 40 or 50 miles if I haven't brought water or food.

I'm still amazed at what we can do with even the most basic equipment. Everything else is gravy.
