When I was a teenager I used to set myself all sorts of challenges, usually abstaining from something like coffee or alcohol or chocolate for x number of months. but sometimes memorising a poem or reading a book (I sill have an open challenge from when i was about 11 to read the complete works of Shakespeare.. taking my time over that one).
These days I don't bother, I know what my will power is so I don't feel the need to test myself so much.
