Okay, maybe buying a $40,000 guitar was a bad idea. But it was so shiny, and BB King picked it up once, and...well, it was a bad idea. Try this next time: Create a calendar in iCal. When you see something you want to drop your credit card number on, add it to the calendar and set an alert for 30 days in the future. If, in 30 days, you still can’t live without that gold-plated Han Solo action figure, it’s probably destiny.
