Clean something every time you don't want to get started on a work project. Don't listen to a podcast or turn on the radio. Just clean. Make it as boring as possible, so that your mind wanders.

Every job involves at least a few simple tasks that don't require your full attention, and these make for great productive procrastination.

Reach out to your co-workers when you're stuck.

Any kind of exercise works. 

Break the project you don't want to start into smaller pieces.
