Not to be too preachy, but I would really recommend to people, if you get the chance, to trust yourselves to leap without a net, because that will build the confidence. You know, you might shock yourself with how much you don't need a net because you can catch yourself.
I started walking rather than driving to get my coffee. I liked it so much, I do it for 45 minutes every day... You know those annoying people who are like, 'If I don't work out I feel... ugh'? I might be becoming one of those people.
