Not everybody does things in the same order. My uncle left school at sixteen and got his first job a month later. Then he started a business and got married at seventeen! When he was 25, he split up with his wife, sold his business and went back to school. Then he decided to study for a degree in medicine. At university, he fell in love with another student, and my cousin was born a year after they left university. My uncle and aunt now work as doctors, and they have settled down near us. That's what I call changing your career - and your life!
