Here are the little things that have helped us:
The wonder of the camera phone: I took a picture of dd nursing and then recorded her voice giggling and what-not. Looking at that while I pump and listening to her sweet little self helps a lot.
Don't know why this works, but you know that vibrating jaw thing a baby does to try to get a secondary let down? Close your eyes, picture your baby at the breast and try shaking your jaw like that. In general, visualization rocks.
Pumping before baby eats: remember that baby can get a heck of a lot more milk out of you then the pump can, so a quick session before baby nurses can help you increase supply (if needed) and get more of a stash going. This isn't good advice for everyone; don't do this one if it doesn't feel right, ykwim?
Have something to read, watch, do while pumping. I'm always amazed at how much milk I get when I'm not pay attention!
Positive thinking: "I have plenty of milk for my daughter and to build a stash." "I can provide for her and take care of myself" etc.
You'll do great!!
