All jokes aside I knew from the time I was about three years old, because I didn't have the same emotional reactions they did (getting excited or upset about certain things), and I didn't want to do what they were doing. Everyone I knew liked blue skies, sunshine, beaches, suntanning, having big get-togethers with friends or family, watching TV, falling in love with movie stars or celebrities, wanting to be rich and have nice stuff, etc. They seemed genuinely motivated by all that stuff. All I ever wanted to do was read a book on a beanbag chair during a thunderstorm. It hasn't changed, either.
Most people I know changed their personality or their tastes as they grew up. They changed their hair styles and hair colours, their clothing styles, their favourite foods, their favourite things, and quite often even their values. Nope. For me I've been the same person I was at age 14 for 40 years now, except that I can drive a car and I get to pay taxes.
