If you dont have friends here already, do get enough stuff to keep you occupied. If you like books, keep in mind Doha isn't known to indulge the reading habit, so get lots of books with you. You may not get all the programs on TV too, so maybe if you get a good collection of music or DVDs it would help. Other than that a positive attitude will be a big boon as I found the first fortnight the most challenging here. Once the feeling that you will stay put here no matter what takes hold, you will start appreciating the luxuries here. All the best!
