I'm 25, I'm not sure if the cutoff date is subjective (though I imagine it is). I've been gifted with computers my whole life, and technically being a freelance installer of networks and destroyer of viruses is fulfilling the calling, but nowhere near the degree I'd like financially or otherwise. I took some (seemingly) bunk advice from several people that college is essentially a scam, and a ploy to put people deep into debt for information that's freely available. While it is true that the Internet makes the information itself completely available for one to learn on their own, employers want to see that paper. The degree itself is what you're buying, that's your ticket in, especially considering the jobs that train their own employees in the first place.
I've also studied French and Japanese for about 10 years now, and was offered a chance to teach English in Japan. I turned it down because my wife (fiance at the time) was mortified by the idea of moving to another country and had no desire to learn Japanese. I wouldn't mind translating or a similar occupation, though.
Thirdly, I've thought lately about writing articles for gaming sites or doing the youtube thing. I consider the train for actually making games to have completely passed (especially considering my complete lack of visual artistic skill), and would love to write about my passion of gaming.
To pile it on, I'm quite frankly pretty damned good at the guitar, bass, and drums, and played in several bands from age 14-22. Anxiety issues that arose brought about stage fright that wasn't present before, and playing has become a deeply personal thing that I'm terrified of doing in front of others lately (even my wife). I never had a delusion that I would be a rock star or make a living playing music though.
In short, it depends on whether or not 25 is a fair cut-off year. Regardless, I've kinda made myself feel the heat to wake up and do something about it by posting this, lest it actually be too late before I realize it.
