If you missed yesterday, nevermind.
Writing every day is the best gift you can give the writer who is you.
If you missed three months of writing because you went to Cuba, bought a new house, had a baby, changed jobs, had a hair crisis, painted your street, or opened a peanut-butter factory, nevermind. Just start today. Fifteen minutes.
"The secret to success is counting even the smallest of your efforts, and forgetting even the greatest of your failures." --CJ Krug
