The American poet Charles Bukowski has some lines to resonate with you on your creative woes. Whether you're a writer, painter, photographer, or musician, you know that what he says applied to anyone who has imagination and creativity running through their veins.
So when you do have those days where the creative voice is mute within you, perhaps you'd feel little less sad and bad about it. There is no on and off switch of the flow of the creative juices.
Here's some borrowed lines from the poem "So You Want to Be A Writer":
"if it doesn’t come bursting out of you in spite of everything, don’t do it. Unless it comes unasked out of your heart and your mind and your mouth and your gut, don’t do it... if you have to wait for it to roar out of you, then wait patiently. If it never does roar out of you, do something else... when it is truly time, and if you have been chosen, it will do it by itself and it will keep on doing it until you die or it dies in you. There is no other way. and there never was."
