From Show Your Work: 10 Ways to Share Your Creativity and Get Discovered by Austin Kleon:
Don’t say you don’t have enough time. We’re all busy, but we all get 24 hours a day. People often ask me, “How do you find the time for all this?” And I answer, “I look for it.” You find time the same place you find spare change: in the nooks and crannies. You find it in the cracks between the big stuff–your commute, your lunch break, the few hours after your kids go to bed. You might have to miss an episode of your favorite TV show, you might have to miss an hour of sleep, but you can find the time if you look for it.
