Also I think that everybody should do some "menial" jobs at some point in their lives because more often than not it provides valuable experience of hard, stressful work and a good sense of perspective for when you make it to your dream job.
I'm self-employed but also have the pleasure of working part-time in housekeeping at a certain chain of purple hotels endorsed by Lenny Henry. When I'm at 2,500ft looking at everybody bumbling along with the monotony of life, I'm very grateful that I'm not down there cleaning up the remains of a dirty weekend. I enjoy working - you get a better sense of the 'real' world and a greater appreciation of aviation and all its' priviliges. When I read about 19 year olds jumping straight in to the airlines I wonder just how much they truely appreciate it? I guess it all comes down to perspective...
