financial contentment is relative.... i am earning less than that amount but i have a high standard of living as far as i am concerned. so it is up to you on how you rate your own standard of living. Maybe owning a Lamborghini will be sufficient for you to regard it as a high standard or a mere Toyota Camry will be fine. Generally, living conditions in Doha will be more than satisfied by your QR45,000 salary.

Good Luck!
