I find watching videos of bails and stacks almost more motivating then normal videos. Like the video on Redbull of Macaskill's April 2009 bails shows how much he actually had to push himself to do those lines so then it made me want to push myself as much as he was, despite the huge skill difference.
And you can try visualization and that stuff, like thinking what you're going to do if something goes wrong and make sure it'll be easy enough to bail. Also you could try videoing yourself. When I made a video I realized how small everything I was doing was and saw that if I bailed it wouldn't be that bad.
And pallets are probably best for this as you can increase them bit by bit, although, eventually you'll just have to go for it and hope for the best, otherwise your progression will be pretty slow.
