Poets know how constraints can be used to their advantage(rhymes, etc.). What things do you see as constraints that you could turn into an advantage? Perhaps you live on the outskirts of a big city and spend many hours travelling either on public transport or buy yourself. What could you do with that time? Read an audio book (or a real book), learn a language, use a voice recorder to record jobs you need to do, meditate(if you are a passenger, of course!). Do you have to get up early for work? What's the most beautiful sunrise you can capture on your camera?
What are your constraints and how can they be of benefit to your life? How can those restraints help you create or achieve?
