I go for a 5k run in the morning. Despite it taking a little time from your morning, it'll pay for itself threefold in terms of productivity throughout the rest of the day.

Also, if you work alone and get stuck on a problem or need a little help with being creative (ie: UI design, marketing), try smoking a joint! It might not be as good as bouncing ideas off of someone else, but it's definitely helped me think of ideas I might not have come up with otherwise.
