It's not too late to join.... commit to memorize 2 scriptures a month for the year. (I'm sure you could even memorize a few extras to catch up if you're one of those for whom it wouldn't feel complete starting partway into the year!) I've got one down, 21 to go (I'm choosing to let good enough be good enough and not give up if it's not "perfect," so I'm going with 22 rather than 24 since I joined late.) Here's my second passage for February:
Let them praise the Lord for his great love
and for the wonderful things he has done for them.
