What do you define as a holiday? Do you define it as going away? Do you class it as a day off work? Do you class it as a week or more at home not doing what you usually do? Do you class a holiday as spending time away from everyone and everything in your normal everyday life? Do you class it as spending time with your nearest and dearest? Do you class it as less hours at work?
I believe that what you class as a holiday is different to everyone. Wha one person classes as a holiday can be totally different to anothers. When some people go away they class their holidays as a time to relax others prefer a lot of activities and adventure.
Personally I think that all of the above are all types of holidays. I think sometimes you need some of each. I think that everyone needs a certain type of holiday every so often otherwise what is the point. You need time to relax or have fun away from every day life or else you will get so stressed you will go mad.
I have heard of people even admitting themselves into hospital as they can't cope with the stresses of everyday life so they need a break.
So try and get as many holidays in as you can within reason and it should make you life a lot happier place.
