Working on something else. If I lose motivation in schooling or work, I go play with one of my cars or mess with an old small engine. When I realize I need money to restore the 48 year old car, I go back to playing with servers.

If I don't want to do anything I just read a book and/or listen to some music. Usually some metal, or rock, or bluegrass, or whatever else I feel like at the moment.
