Yeah, even the God-Artists from the past had their share of fears and doubts about their craft. Here's some inspiring quotes from the Post-Impressionist artist Vincent van Gogh.

"I feel such creative power in myself that I know for sure that the time will arrive when, so to speak, I shall regularly make something good every day. But very rarely a day passes that I do not make something, though it is not yet the real thing I want to make."

(Letter to Theo van Gogh, 9 September 1882)



“In both figure and landscape … I want to get to the point where people say of my work: that man feels deeply, that man feels keenly.”

(Letter to Theo van Gogh, 21 July 1882)



"As practice makes perfect, I cannot but make progress; each drawing one makes, each study one paints, is a step forward."

(Letter to Theo van Gogh, c.29 October 1883)



"Painting is like having a bad mistress who spends and spends and it's never enough ... I tell myself that even if a tolerable study comes out of it from time to time, it would have been cheaper to buy it from somebody else."

(Letter to Theo van Gogh, 23 June 1888)
