For me, what worked was just to sit down and work it out for myself. I never do very well from demonstrations, although they have been helpful with more advanced stuff. That way I could find a spinning method I understood, which suited me. I explored the qualities of wool, how it draws out, how it sticks together, how much twist you need (all from finger spinning), different fleeces etc, before I ever tried the actual spinning. I always like to really understand something, because if I don't know why something happens as it does, and I just copy what I've been shown, then I find it difficult forever. There's no 'right way' to spin, just what works for you. Suddenly it will click. So my recommendation is to practice every day as Sally says, without trying to follow the instructions you've had too closely. It sounds as if you are getting very tense and annoyed at the whole business - spinning never turns out right if you're uptight, so just relax and accept that it will take a few weeks of practising for a short while each day before you can produce a recognisable yarn.
