Every morning for the past several years, the first thing I do is complete the mini NY Times crossword puzzle. I have a competition on who can do it fastest with my brother and father and send them my times when I am proud of them (anything under 40 seconds). I usually can tell how smart I am going to be that day based on my success on the mini crossword. I have it as an app on my phone, but you can also do it on the computer. It is fun, addictive, and not time consuming — which I love!
