if your not happy, then that wont likely change until you start doing something that does make you happy.
Its not all about money and lifestyle... in fact, make sure your happy first, then lifestyle will follow.. Money will not make you happy, just read the newspapers every day to figure that one out.
you only get one shot at life so dont waste part of it being unhappy. i was unhappy at QF for many years, the day i left was the best day of my life. if your happy, then everything improves, relationships, friendships, general well being, all far more important than money and lifestyle.
