Переведите пж!!!!!!!!!
Everyone needs at least one holiday a year, so when you begin spending sleepless nights thinking about the sun and the sea, when you think longingly of the green countryside and forget the mosquitoes and the boredom, there's no doubt about it – you're ready for the holiday.
Even a week-end is better than nothing. You need to get away from all your usual routines and get some fresh air and a change of perspective.
You should also take occasional holidays without the family. Husbands and children can do very well without you for a limited time and, if they cannot, they must learn to. It will be good for them to realize how much you do for them during the rest of the year. It is necessary for children to realize at a very young age that they can do without their parents. It teaches them independence.
Go somewhere quiet, where the climate is pleasant and invigorating. For the first couple of days, rest and sleep as much as you can. If you are in he mountains, give yourself a day or two to get used to altitude; by the sea, have a daily swim.
Do things the way they are done in the country you are staying and eat the local food. Get to know the natives and their customs. Do a little sightseeing, even if you do not like it. Always have a dictionary of the local language, and pick up a few words. It is a good idea to get to know the place as well as you can.
If you prefer complete solitude, take some books and catch up on your reading.
You should try to store up energy and vitality to see you through the winter months. Be willing to put up with small inconveniences, and don't allow yourself to be annoyed. Things will not be done in the way you do them; so much the better. Take note of the good, and pass over the bad in silence.
Try to learn something useful from your holiday. Bring back an unusual peasant recipe or a local pottery jug. Don't burden yourself with a camera unless you are a genuine enthusiast; you will be always looking through it instead of directly at what is around you. And don't indulge in that useless habit of sending holiday postcards – if you forget all about home, you will come back with far more interesting tales to tell.
