No idea what this is!
I don't know much about plants in general. This succulent seems to have red tips and a stem with buds that may possibly flower? The stem also has small thorny protrusions.
This is a flowering Echeveria of some kind, but not sure which one.
They are all nice, so whatever species it is, you can't go wrong. You can find out more about them here: Echeveria and its species and hybrids.

Hope that helps with getting your addiction to plants in general, and succulents in particular started!
