I'm afraid that the creativity will run out. Just dry up. Like one days it's here and the next it's gone. Of course this is a silly thought. But don't most of us who make a living designing things depend on our creativity? Well, some would disagree. But you see my point? If our creativity were to just dry up where would that leave us?
Then it's a good thing we're not responsible for our creativity. We do not have control over our own creative ingenuity. It comes to us as a gift in many different forms and fashions. And thinking of it in this way helps free us from any guilt or judgements we want to put on ourselves. Like I've said before, let's allow ourselves to have all the stupid ideas we can muster, so when the good ones come along we can make room.
