A pitfall of planning well ahead is forgetting at the last minute: You scheduled a tennis court two weeks ago, then spaced on it last night. To avoid this scenario, schedule the delivery of text messages to remind you (or someone else who needs reminding) of the day and time at MemoText, www.memotext.com. Write your own daily, weekly, or monthly message, or sign up for MemoText�s holiday or favorite-TV-show reminders. Think of it as a high-tech update on the piece of string tied on your index finger — only it actually works.
