look around you and look at the positives. I don't always like my job but it's paid for everything I have.. my kids, my clothes, my house,its contents, my car, our holidays, etc etc.
sadly, most of us have some health issues to complain about but some people are really suffering.
look around you and be grateful for what you have, there are plenty who would envy you.. and if it's really not enough for you, you need to decide what you're going to do about it. we don't all have the luxury of choice.
