I'm not sure how other people deal with this but I find the way that works for me is to draw a picture in my head of rolling hills. Tall blades of grass represent stacatto, smooth plains represent legato, chasms are silence... Am I weird?
For example a piece that starts staccato and forte, then decrescendos to legato and piano, then ends staccato again would look like this in my head..

What does everyone else do to remember?
