It doesn't matter how much time you have, productivity is how much you produce in that amount of time.
Everything I do should be with the intention of creating a specific result.
Don't be a perfectionist. Plan ahead and put everything on a calendar. Give yourself a time limit and be done when the time is up.
Not everything you create will be great. But being highly productive (quantity) is great practice and increases quality naturally.
Ask yourself: How can I spend less time consuming and more producing?
