Finding inspiration

Every now and then every artist suffers from a lack of inspiration - I think...
I have a creative block every now and then when I just can't seem to come up with any creative ideas of my own, however I am still able to create art on request and most of the time this helps me get through a creative 'block'. Not being able to come up with any original ideas or concepts of my own can be quite frustrating though, as I wade my way through a seemingly thick marsh of empty, black nothing...
Through the years I've tried to find different ways to overcome a creative block and some of the below is a couple of things that have helped me in the past:
 - browsing through other artists' artworks, online, in magazines
 - browsing through some of my own 'forgotten' old artworks and finding an image or design to 'redraw'
 - doing a Google search of a theme or object and choosing an interesting composition to draw it in a new way 
 - listening to music and letting my mind's 'eye' wander over the images that gets played in my mind
 - redrawing a favorite art-piece from a favorite artist in my style
 - creating a prompt list, or following someone else's prompt list, of things to draw (something like Inktober)
 
These are just a couple of things worth trying, but most of all, I've learnt not to stress about a lack of inspiration too much as this seems to aggravate the situation even more. And trying to force inspiration can sometimes backfire and affect my ability to even paint or draw! 
Being an artist is not always sunshine and roses, sometimes its sweat and tears. And sometimes, as an artist, as soon as you find inspiration to draw or paint, your time is filled with the other important things of life.
Don't despair though - there is tomorrow, and new inspiration for a new day!
