Regardless of how good or bad a person’s memory is, I think everyone needs some sort of a planner. Life can get so busy and hectic sometimes that you won’t be able to keep up without something like a calendar or organizer to help you do so.
SUCK UK Calendar Tape by Laboratorium is a cheap and practical way of keeping your schedule together. Use it as a Twitterish diary, an organizer, or yes, a calendar.
You can also mark your video games, CDs, DVDs and gadgets with it, so you know when you bought them or when they’re due for maintenance, when to give/sell/throw them away etc.
