You say you are not a big spender, therefore 25,000 QR is not a bad salary. I don't know where some of these people work but I assure you that on 25,000 QR you can live quite well and still save money. Buy a car it's not that big of an expense and more convenient than using taxis all the time.

Light travels faster than sound. This is why some people appear bright until you hear them speak.
