Besides the finding something that you enjoy part (and given that that makes you good at it) there was this second part - something that is work for somebody else. He probably should have mentioned that there is an implicit third part - finding and convincing somebody to actually pay you for doing this work, plus a fourth issue - the competition. However, there are careers in soccer, not sure about hiking though, that's more recreational, you might make a teaching business out of it though.
