I'm about to head out and buy my fourth combination lock this year. Turns out a combination lock is only as good as its ability to be opened — and recovering a lost combination is virtually impossible. Because I am forgetful and my gym-going habits are somewhat sporadic, I've managed to forget the combination to three separate locks. So, as soon as I purchase my fourth and final lock of 2010, I will email myself the combination.
I often email myself important dates, details, or phone numbers but have never thought to do this with a lock combination. Of course, this will only work if you use a searchable email program like Gmail or have an effective filing system for your mail. I plan to title the email "Gym Lock Combination" and include the date to avoid any confusion. Now, as long as I can keep track of the actual lock, I'm in good shape!
