If you’re a writer, you’re writing 24–7–365. Everything you read, see, and experience is material for your writing.
Pay attention and live deeply. Take lots of notes—on index cards, on your phone, on a napkin, wherever. Draw stuff. Make voice memos. Keep it all organized.
Some days, you’ll have 15–30 minutes to type it out into something you like. Others, maybe 5. Time has a funny way of opening itself up—when you’re waiting in line or for a friend who’s running late, when a meeting gets cancelled, when you feel inspired at a coffee shop.
And it might not be your best work, but it’ll be enough.
