When in doubt or perhaps stuck as they say, you might as well do something. It's better than nothing and it feels like you did SOMETHING which is better than nothing.
On a more serious note, it is good to ponder as well. Sometimes though that has to end. Sometimes you search endlessly for the thing you want. You think the one thong is THE THING and for some reason, it just doesn't quite feel right. In this case maybe doing nothing was good. Then one day, THE THING is right there and it really does feel like THE RIGHT THING! And probably it is. The old adage about if it doesn't feel right don't do it may really work.
Plainly, I have contradicted myself in a big way. Maybe what I mean is divert your creative attention in another direction when doing something, while waiting for the light to gently shine on you.
