Yes! You must learn to do everything knitting. That way you can teach me!
I'd seen that video for socks before and found it off putting, went on and found the Lifestyle socks that are mentioned in the video Jan linked to. Thanks for the video, Jan, I'd seen it or something like it before but didn't quite catch on...that was when I hadn't actually done a sock yet I think. I think Silver's Sock Class pretty much gives you a how-to for socks and you can then do them without a pattern. That's what I love about socks, no pattern required unless you want to do something fancy. Personally I like ribbing around my foot, I think on socks from the store it was called an arch support. I like the way it feels snug, not tight, and helps keep the sock in place and the top doesn't get eaten by my shoe. That's something I wanted to learn, so I did. Learn what you want as you need or the spirit moves you. Sometimes you might end up doing a few things you'd rather not simply because you want to do a particular project. It's kind of like life, sometimes to get what we want we do a few things we'd prefer not to do.
Learning to knit English style was a biggie for me. It still seems awkward, but I can do it. Why bother? So I can do colorwork and carry the second color in my right hand. Was it worth the effort? Yes. Will I turn into an English style knitter? Probably not, but if I injure my left hand I should still be able to do garter stitch, I still can't purl English. I plan to try that odd looking provisional cast on followed by short rows toe, someone on the forum said they like it. I might. I do think you might want to look again at provisional cast ons, they come in handy in various places. Or not. It's up to you.
Frankly I'm amazed at how much knitting you can do with young 'uns. If your comfort zone is to do what you've already learned, stick with it. If it ain't fun, why bother?
