Tubular What?

I think I have reason to believe that I may be an idiot. Hear me out, I wanted to do a tubular cast on for the mittens I am making for my partner, so I looked it up on Google and found this cast-on. Now the first time that I cast on, I read the directions all wrong and ended up with only two stitches spinning around and around, and then a tangled mess. But I persevered and re-read the directions and cast on again, this time I got it, but when I did the set up rows, I totally screwed up. I ripped back and cast on again (3rd time here people) this time it was perfect, I even removed the yarn and the whole thing...then I realized...WRONG SIZE NEEDLES! Idiot! I ripped it out and cast on gain...apparently 4th time's a charm. This whole process took about 2 hours! Yes, two hours of wasted time because I, like an idiot, cannot read directions. Lovely.
