Know that attitudes and feelings and thoughts often change, and that what felt right one day can often not feel right the next.
Know that no matter what you create, plan, or schedule, feeling happy about it all should always take precedence over that feeling of urgency to just get it out the way.
Know that just because you've decided to put something off doesn't mean it's bad, or rubbish, or not good enough. It just means it wasn't for today. Tomorrow? Who knows.
Know that YOU can do what you want, or don't want, to do. Because this is your life, your space, your work, your time, your effort. Don't let something or someone else dictate that for you.
Know that sometimes you'll end up spouting words of nonsense and that, no matter how hard you try to change them, they'll always be nonsense.
Know that, sometimes, nonsense works.
