Find a daily action partner. This will be the person who you check in every day with about the plan you made in Part 2. Call them every morning, state what you will do for the day, what might get in your way, and what you will do about it. Your action partner should be someone you can discuss your logistical issues with as well as emotional issues that may come up in response to the new level you're working on. Let your action partner know that what you'd like from them is to listen and be supportive and to call you out when you're off-target. Know that just taking the action to call another person who really gets what you're working toward will bring you strength.
Each time we move up to a higher level of productivity, creativity, or integrity, the part of us that has been stuck can get scared. You can address that part of you by actually talking to it, respecting it's concerns, and giving it a voice. Once you've done that, "mine" what your inner critic has told you. (Don't bother arguing with it; it's not reasonable!) Is there anything your critic said that you can use creatively? Sometimes our greatest treasure is the same thing that holds us back. If your critic were giving you a gift, what would it be?
After you've listened to and mined your critic's message, move on. You can even set a timer for, say, five minutes, to listen to you critic. When time's up, set it aside and begin your creative work.
"Friendship improves happiness and abates misery, by the doubling of our joy and the dividing of our grief."
