I've never really thought about it as inspiring, because it's just been "life." I try to do things I'm interested in and then when circumstances change, I look for something else.
I have a friend who was a tour guide and fitness trainer for many years. He's climbed Kilimanjaro something like 12 times. Now, in his early 40s, he is well on the way to obtaining his commercial pilot's licence. It's something he's wanted to do since a teenager and has saved towards that target for a long time. To me, that kind of dedication is inspiring.

You really should write a book or something like that. I'd be happy to read it.
Inspiring!
