What my instructors always said about getting off the lift: put your back foot on the board, look straight ahead (or where you want to go), stand up straight and relax.
I also hold on to the lift for a little longer to let the people sitting next to me to get off first. They always cut me off for some reason (goofy rider, I sit on the left side of the chair). But they're usually my friends so I forgive them :P
I hope you have an easier time with this soon
