I generally try and have tasks of different types available for different moods (eg bug fixes, graphics work, marketing, etc). It's important for me to keep the momentum going though and even finishing a small thing is better than nothing. Some things just require more time/thought though, so sometimes I have to shelve things and tackle them when I have more time. Sometimes all I get done in 30 minutes is to make a decision about how to do something - this is still progress and feeds into the next spot.
