Great ideas in Rob Walker’s The Art of Noticing:

• Write a letter to a random person and leave it anywhere.
• Write a book about your memories. Write what you remember, without further research.

Many (of my) ideas are too big and, as a result, execution takes far too long. I don’t finish them.

Just today I killed a couple of big ideas. One I chopped up into small ideas, with heads and tails.
