Nulla Dies Sine Linea.<p>Never A Day Without A Line.<p>Advice given to Roman artists. Create art every single day of your life, even if that art is but one line.<p>I myself compose for and play the piano. I enjoy it but it is tough to make forward progress; if one plays only for pleasure one is unlikely to advance.<p>After someone said to me "Nulla Dies Sine Linea", I used Adobe Illustrator to draw an 88-key piano keyboard, then placed that on a poster with the advice, a neat border around it, printed it on pale grey cotton resume paper, framed it then mounted it on the wall just above my keyboard.
