Yes, I learnt to read age 2, was moved up a year in school, head girl, etc. etc. Got to university, sex and drugs, mental health problems, whoops, dropped out completely, no degree.
Schlepped around for a few years on the dole, then drifted into childcare which I loved and was very motivated about. Spent 10 years as a nanny being asked "Why are you doing this, you're quite intelligent?" I still like to use what's left of my brain, but never been ambitious in the conventional sense. However was offered £60 for an hour's work yesterday so I can't be a total failure.
