I agree. Confidence when picking up your snake is a big part of it. If you're nervous about getting nipped though, and would like to avoid the experience for a bit longer, I suggest picking up a small snake hook from your local petstore. They are around 10 dollars and wonderful little tools for a nippy snake. Obviously this won't work once they get bigger, so confidence when handling is key. But a snake hook is always an option. Just make sure its end is blunt and not sharp, so as to pick them up without harming them. And never pull them off of a climbing branch, or poke at them with it. Just loop it through a coil and up they go!

Good luck!
