I’ve heard from people who live up north that the key to getting through a cold winter is to get out in the weather rather than try to avoid it. Bundle up and go walking through the wind and snow. Be proactive, take the initiative. Be on the offensive, not the defensive.
That’s pretty good advice for a creative stance in general. So you have a day of meetings; put on your “meeting” clothes and dive in. You’re tired, sniffly, and out of sorts—for heavens’ sake, enter your poor body and put it to bed and let it sleep until it feels better. The day calls for problem solving; turn into a detective, a counselor, the captain of the moment who devises a plan and pulls other people aboard to accomplish it.
Go into this hour face first. Move toward the problem, wrestle with the idea, have a direct conversation with the emotional self or the intuitive self or the hostile self. No one else will be you in this day. No one else can bring your gifts to this opportunity.
Creativity does not thrive on fear or defensiveness. That part of your personality is made for challenge, exploration, with arms open to the world.
