In the long run, you'll become an expert at casting on, since you will frog more pieces than you'll finish. So, eventually it will become easy.
I recommend finding somone live to help you with casting on. You may be doing some little quirky thing which someone in a knitting store or a friend or someone at church or somewhere will be able to catch.
I almost always use a knitted cast on - and it was the only one I knew for over 20 years of knitting. I just recently learned there were other ways and figured out the thumb cast on. So even if you end up with one you can figure out and you only use it for 20 years, you'll be fine.
