Keep a word journal or notebook to collect what we call word treasures or word surprises. Use the dictionary or thesaurus to find words you are curious about, like the sound or meaning of words that inspire you, surprise you, make you laugh or touch your heart. Words that knock your socks off.
Explore how certain words make you feel. What emotions do certain words bring up? Look into the origin, the history, the meaning. Jot them, doodle them, keep them in your word notebook for your very own. (You might never actually use them in a poem, but then again, you might.) But the real reason is to revel in words: collect them in one place, go back to them, add more; rejoice in the wonder of small treasures we call words.
