I see that, but I didn't do 4 years to qualify me for teaching for my husband and then my own health to deteriorate massively so I'm unable to do what I love... But you make the best of it. I've always said to my children it doesn't matter if you're the King of England or the road sweeper, it's really important to do the best that you can.... What if the cleaner in the hospital doesn't do their job well? Or the nurses? Maybe you just have to remember that although it's not the perfect job you want, but right now it is putting food on your table, a roof over your head and actually what you think is a rubbish job might be the most perfect job that someone else might be desperate for.
The most humbling thing when I was teaching a group of year 10 - 11's at a school for those with severe learning difficulties. One of the things we did was go out and about in the community building social skills. One of my students dream job was to work in McDonalds. Every time we ever went in there he was so excited that he just couldn't even talk and go up to order his own drink without support...
