I think that the best way to learn is just to keep practicing. If your nervous just buy some cheap knives with reasonable carbon steel blades, something like an opinel or a mora, then you won't be inhibited by the worry of damaging and expensive knife. In general its much easier to get a decent edge with a carbon steel blade than a stainless one.
Just remember that what you are trying to achieve is a clean non-rounded angle at the edge. It might help if you cover the edge with black marker pen and try to 'sharpen' it all off right to the edge, you will be able to see shiney metal showing through where you are removing material. A magnifying glass can be helpful here as well. But don't be confused by all the technical talk that goes on, just go for it, try to keep the angle between the blade and the stone as constant as you can and you'll get there soon enough.
The happiness of a man in this life does not consist in the absence but in the mastery of his passions.
