Being an Android fan, I get the urge to buy an expensive, shiny new object roughly every three to six months. If you're in the same boat, put a one month moratorium on that buying decision.

As tips blog Lifehack points out, taking a month can give you plenty of time to reconsider whether or not it's something you really have a desire for:
When you think you want something, put it on the planner a month from now. When that month rolls around and you still want it, OK.
Of course, you can also use that month to save up for whatever it is you're planning to get. If, in that amount of time, you decide you don't really want it anymore, check it out! Extra savings!
