Will post here those of written by me, which are somewhat related to behavioral economics/finance and as such, to trading and investing as well. One man lived on a lonely island (nobody knows how he got there, even himself, most likely his ship crashed, he survived, but lost memory about the case)... he dug out wild potatoes to eat. Usually there was enough, but from time to time he ran out of plants to find and dig the tubers out. Once he walked down the hill with few potatoes in his hands, one fell out, rolled back and got lost in the grass... "oh well", thought the man and forgot about that. A few weeks later he walked down the same hill and suddenly saw... blooming plant of wild potato in the place he never thought it would grow. Then he recalled the lost potato and said to himself "to forget about tuber fallen in fertile soil is better than find one"...
