Margaret AtwoodI was hoping all ten would be about pencils.
1 Take a pencil to write with on aeroplanes. Pens leak. But if the pencil breaks, you can't sharpen it on the plane, because you can't take knives with you. Therefore: take two pencils.
2 If both pencils break, you can do a rough sharpening job with a nail file of the metal or glass type.
3 Take something to write on. Paper is good. In a pinch, pieces of wood or your arm will do.
It turns out my release of 6 CryptoArt works consumed in 10 seconds more electricity than the entire studio over the past 2 years.
