How about not pushing kids into anything but instead giving them a wide set of interests and seeing which ones they like the most and then encouraging them to pursue what they really love most?
I've been a techie since I could walk but my daughter loves biology to bits, I've had to learn to suppress my ultra-squeamish tendencies in order to encourage her. You're talking about a bloke who threw up in 5th year biology class when he was asked to dissect...a sprat! Yes, I didn't even have the stomach to carve up a tiny pilchard sized fish without vomiting. so heaven knows where my daughter got her love of biology from!
