Most knitters are self-taught. I taught myself after seeing someone knit continental style, and looking at pictures in books. It is not that hard. It takes persistence, that's all. You need to practise slowly, to create muscle memory.
Check out YouTube, there are lots of examples of continental knitting. There are as many ways to knit as there are knitters. I am not going to say that there are wrong ways to knit, but there are certainly ways that are better in terms of efficiency of movement. Knitting is a repetitive motion, so keeping arm and finger movement to a minimum is beneficial - it reduces the risk of injury. If you find that you are poking yourself, or getting sore somewhere, you might want to check what others are doing - try something different to see if it helps.
Anyways, here are my offerings to the continental knitting video world...
