I didn't mean for my comment to be condescending - sorry about that.

I was a computer programmer from 20 to 21 (I worked full time in college), and I changed fields at 21. I am in my 30s now. I didn't figure out these dynamics by myself - I was fortunate that my manager at the time was also changing fields, and he explained these things to me. He was in his early 30s and he became a doctor.

Now I am just trying to return the favor by describing these things to younger people on HN. And I read HN for kicks. :)
