@Timecircleline I'd recommend a hat. It's quicker than a scarf and you learn lots more from it (eg: decreases).
Also, if you come from crochet, take a look at continental knitting! You tension the yarn in your left hand which is more crochet-like.
If a long tail cast on (probably what your mum was trying to teach you) was too much at once, try a knitted cast on: put a slip stitch on your left needle, knit it but don't slide it off, put the new stitch next to it on your left needle, repeat.
