Vacations are not really the luxury that people think they are. In fact, if you think about it, taking a vacation at least once a year is the sort of thing that you kind of have to do because of the fact that it would give you the rest you need in order to truly do your best at the job that you are trying to excel at. Employee burnout is a very real thing, and it can compromise your effectiveness at the job you are trying to do.
The good thing is that if you go on a vacation none of these problems are going to matter anymore. You would probably want to try and make your vacation as good as it can be though because it is your only chance to get the rest and relaxation you need. Anything could go wrong at any given point in time, so trying to figure out a way to plan your trip in advance would be something that is worth doing.
You could always write down a list of things that you plan to do but creating an actual itinerary might just be more useful for you all in all. You can visit Realia Project.org to get templates for itineraries, and once you fill one out you would see just how immensely useful things like this can be if you know how to use them properly.
A properly constructed itinerary can actually be more effective than just a normal list because it would leave everything looking properly organized to the point where following the itinerary is going to become a real breeze for you. Once you have planned your trip out you can be sure that it will go well.
