Open a book you have been reading, to a random page. You may have to go beyond this page unless you are lucky, but from this text collect some “interesting” words. (Define this as you want.) If you don’t enjoy the process of search and seizure, stop at four or five.

Deposit these words in a bank.
The next time you draw a blank when you WANT to write, pull one of the words and find out everything you can about it.

Try writing lines, sentences, fragments that use the word in different ways.

Maybe include more than one angle on the word within the course of a poem. But don’t point to what you are doing.

Deposit new words, from other sources, now and then.
