You can write any time people will leave you alone and not interrupt you. Or rather you can if you will be ruthless enough about it. But the best writing is certainly when you are in love.
Find what gave you emotion; what the action was that gave you excitement. Then write it down making it clear so that the reader can see it too. Prose is architecture, not interior decoration, and the Baroque is over.
You've got to sell your heart, your strongest reactions, not the little minor things that only touch you lightly, the little experiences that you might tell at dinner.
