As someone who has applied for over 1,000 jobs in the past 5 years - received 4 yeses, 2 nos and the rest completely ignoring me - I know how you feel.
I think the gist of it is that even if you don't want the job, you see absolutely no reason why they should not want you - after all, you are great.
I once wrote this as irritated response.
What Qualities do you have that make you suitable for the job?
I'm an enthusiastic, lively person with a good sense of humour. I am not scared of approaching strangers and have found myself to be very skilled at talking to customers, frequently having customers who have returned just to speak to me. I am confident with conveying and presenting ideas, whether it was bringing history to life on the top of a bus, or presenting ideas at small meetings with the university student union. I have a flair for performance but am also a good listener, and often seem to find out more about strangers in a short time then most other people. I am smart and intelligent. I can pick up new sequences and ideas quickly, and can apply them to situations without being prompted. I can think for myself and use both intuition and reason to think of sensible and workable strategies. At the same time I do not have a problem with taking orders or following a 'house style'. I am rigorous in cleanliness, though I tend towards casual friendliness over formality. I have a good way with words, both spoken and written. I can understand complex ideas easily and then break them down into simpler ideas in order to explain or pass them on. I am reasonably fit and can stand up all day, reasonably strong and can carry objects of a medium weight. I smile a lot and am nice to have on a team. I am creative, I can think of new ways of doing things, or just to entertain. I am reliable, I can be given a list of tasks and will move diligently from one to the other without being told to. I learn very quickly, and it doesn't take me long to become acquainted with the stock and to converse authoritatively with customers about it. I would be an asset to any team, friendly, funny, affable and intelligent. Not that it matters because you'll just ignore this application anyway and employ your aunty's friend's nephew.
