How can someone become more autotelic?

Hello everyone. https://en.wikipedia.org/wiki/Autotelic Being autotelic is what everyone suggest to be in order to live an happy life. "Follow your passion, don't pay attention to other's judgment..." basically everyone say those things. Well, watching some really cool videos here ( https://vimeo.com/delvetv in particularly in the third part of "Long Game") I stumbled in a new word: autotelic. Being autotelic basically means that you get a rewarding feeling just because you are doing what you're doing. (I'm not very good at explaining, you'll have more luck with wikipedia).

And now the big question: how do you become more autotelic? Can you improve it, or you are born with it? And anyone can be autotelic doing everything?

P.S. I apologize for any mistakes, but English is not my first language. And I'm also sorry, because that text isn't an advice or anything, but just food for thought. I only want to pursue the matter.
