People are fond of spouting out the old clich%uFFFD about how Van Gogh never sold a painting in his lifetime. Somehow his example serves to justify to us, decades later, that there is somehow merit in utter failure.
Perhaps, but the man did commit suicide.

Everyone is born creative; everyone is given a box of crayons in kidergarten. Then wen you hit puberty they take te crayons away and replace them with dry, uninspiring books on agebra, history, ect. Being suddenly hit years later with the 'creative bug' is just a wee voice telling you, 'I'd like my crayons back, please.

If you try to make something just to fit your uninformed view of some hypothetical market, you will fail. If you make something special and powerful and honest and true, you will succeed.

You have to find a way of working that makes it dead easy to take full advantage of your inspired moments. They never hit at a convenient time, nor do they last long.

Neither should you fret too much about 'writer%uFFFDs block'. If you%uFFFDre looking at a blank piece of paper and nothing comes to you, then go do something else. Writer%uFFFDs block is just a symptom of feeling like you have nothing to say, combined with the rather weird idea that you SHOULD feel the need to say something.

If you have something to say, then say it. If not, enjoy the silence while it lasts. The noise will return soon enough. In the meantime, you%uFFFDre better off going out into the big, wide world, having some adventures and refilling your well. Trying to create when you don%uFFFDt feel like it is like making conversation for the sake of making conversation.
