Going at your own pace sounds like consolation until Jane Selwyn-James explains why it is a method. She writes for people fitting a business around a job or a family, and insists that comparing your rate of learning with somebody else's is the fastest way to stall completely.
Her post on identifying an avatar is the one to read first. She separates the idea from customer profiling, defines the avatar as the person you would want as a partner rather than as a buyer, and then makes you write down what that person already understands.
A related piece asks whether the failure people feel belongs to them or to the model they were handed, and she does not resolve it comfortably.
Copywriting, affirmations and the Chinese bamboo that spends years underground before it appears round out the mindset side. There is also a post on gallstones, which arrived from her own life rather than her business.
Write down your avatar before you write anything else. That post alone justifies the visit.
