Jump Rings

I've just started jewellery making and am finding it hard to put my trust in jump rings?  Why is this?  Almost every piece of jewellery that I own has them on and other people use them, so why is it that I can't trust them?

I wonder if there is a phobia of jump rings, and what would it be called?

Here are a few photos of my first necklace.  Amazingly it's sold already!

I didn't even get a chance to give it a name :)
