You shouldn't direct your kids towards a career - what they are good at now, may not be where they want to be. At 12/13 my son wasn't interested in some of the subjects he loves now at 16. He still doesn't know what he wants to be, but we will always let him choose the subjects he wants and advise him as necessary.
I hated IT at school and tried to avoid it. At 35, I have discovered I am a bit of a whizz with computers and databases!!
