It seems that most people who create have an even bigger problem with the bit that comes after,
namely pushing their creation out into the world with confidence. The crass way of describing the process is "Selling Yourself".
Some of the most talented artists are riven with self doubt, always believing it could have been better, that somehow they haven't quite captured the initial inspiration.
The trick is to accept frustration of that process, accept that perfection is inachievable, and offer the world your work anyway. NOT EASY!
