Create a checklist right now. Write down all of the things you think you need to do between now and the day of the big event. Of course, not all parties need a comprehensive list with timing deadlines. For example, if you were throwing an impromptu get_together with your friends, and you were doing a Mexican_themed party, with Mexican food and margaritas, you would want to make a list of everything you needed from the store. Granted, this is an oversimplification of what goes into planning a party, but you get the idea. The list will help you to remember everything you need for your party to be a success. When creating a party planning checklist for a really important event, like someone's 50th wedding anniversary or a retirement party, there are two extremely important items you need to have on that checklist before anything else: the budget and the guest list.
Do you want to go camping with friends, family and your romantic partner? Has this been an idea in the making or spur of the moment? Either way, one of the best things to remember is to prepare.
