Knitting is one of those things that is very stressful when you are learning, and very relaxing once you get into the flow of it. From my unscientific research at least 70% of knitters learned how to knit, then forgot, then relearned, then forgot, about 6 times before they truly got the hang of it.
Beware the pitfalls of trying too many new things when you are first learning. Stick to the basics and you'll be fine.
Once you get knitting and purling under your belt, avoid the terrible rut of never trying anything harder for the next ten years. Once you have a solid foundation, then it's time to explore, go crazy, learn some new patterns, etc. Knitting is notorious for an easy looking end result being a holy terror to knit, or seeing a complicate design that turns out to be relatively simple to knit. Fortunately, most patterns give you a heads-up with a subtitle that says Easy, Medium, Hard or Beg. Intermediate, Advanced, or some such. The scarf in the photos in GIGI yarn is easy. It's only 8 stitches. Cast on 8 stitches. Knit each row until scarf is a length you love. Cast off. Using a yarn needle, weave in remaining ends.
The only hard part is long haired yarns like to tangle, so if you are totally new to knitting, use a basic smooth yarn for your first go at it.
Also, you might like organic knitting. That is knitting w/o a pattern, just a concept in your mind. Let the piece evolve as you go along. If you make any mistakes, try to turn them to your advantage. At the very worst you can rip it out and start over. And you'll love your one of a kind design just knowing it's the only one out there.
