Well. I don't watch much TV or movies or other stuff (in fact we don't even own a TV), but we do have some DVDs of things we enjoy. Among them are things with Nathan Fillion.
This is due to a present from a friend of ours, who gave me, many birthdays back, a DVD with Dr. Horrible's Sing-Along Blog on it. (Fantastic. If you like weird, go for it. It's only a good half hour. I will wait here.)
We liked it so much that we looked for other things with the same actors, and that led us to watching Firefly, plus some other things, with Nathan Fillion playing a (usually big and important) part.
And now, by chance, I found out he got an honorary doctorate and gave a speech, where he gave his three steps to success.
Some of this certainly sounded familiar. I can't count how many times there was something that I was slightly (and sometimes more than slightly) scared of, and I did it anyways, and it was the Best Idea Ever. (Or maybe not quite that, but it definitely was a very good idea and I never regretted it.)
The Textile Forum. Quite a few of my workshops. Going to fairs. Going for being self-employed. Committing to writing a book with a colleague on another continent, whom I barely knew at that point. All glorious ideas, in the end.
So, from my point of view: The steps he gives are entirely valid. And I would add that in my personal opinion, they are not only valid, they will make your life nicer (gratitude tends to make everything more friendly, and more mellow, and you will have kinder people around you if you are kind yourself) and more interesting. (Even if it's a little scary sometimes.)
