From another messy, unartistic and anxious barista, you won't really get into it till maybe 3-4 months in. The other baristas know that, they should understand.

Make cheat sheet cards for bar!! I have a few for shots and syrup #s for all hot/cold sizes, and one for specific recipes like a macchiato. Helps me tremendously when I second-guess myself on simple things and I don't have to ask someone if i'm doing it right every 10 seconds. And don't rush yourself at first. You may be slower at making drinks but it's always better to have them wait longer for a correct order than messing up and having to start over because you wanted to be fast. Or worse, burning yourself. You don't have to be fancy about the drinks or latte art, they all come with a lid anyway and most don't notice. So no pressure on being artistic!

Also, ask questions. No matter how small, even just to make sure you understand them. For the first few weeks they'll probably pair you with an experienced partner who can support you. You should be able to ask anyone nearby though and most are willing to take a second and help out. If everyone gets annoyed by your being new that's a problem for management, because having partners support each other is a huge part of learning the ropes. If you're overwhelmed on a certain position (drive through can be a lot sometimes), let them know and ask to get switched out.
