For a lot of people I think this fear of not measuring up is what stops them from pursuing their creative interests. It's easy to look at what other people are doing and think "what could I possibly add to that?" The problem is that when we let those thoughts get in our way, we not only deprive ourselves of the joys of creating and sharing our work, but we also deprive our audience of experiencing it - whether that audience is a craft show or gallery customer, or your best friend admiring the card you sent her, or your husband appreciating how you redecorated the living room.
