And then you organize the rest of your day around the thing you decided to make the time to do.
The truth is, people don't "find" the time to write. Just like you don't try to "find time" to see your significant other, and you don't try to "find time" to go to the gym, or see your old friend from college with they are in town, or see your parents on Christmas. When something matters to you, you MAKE the time. And then you organize the rest of your day around the thing you decided to make the time to do.
