What have you done that makes you say, "If I did it, anyone can!"?

I’ve accomplished a few small things in life that I’m proud of and that I think others could do if they tried. One being that I finished school. I haven’t gotten a degree, but I did get a certificate, which is a lot considering my past lack of ambition in formal education. I genuinely feel that if I can do it, anyone can. I have a few more things I hope to add to my list before I get old and dusty.

Is there a goal that you reached after thinking, “I’d never…”? What’s something you’ve accomplished that you would encourage others to do?
