That's the spirit! I myself am one year younger than your programming carreer and most of the time I struggle with new technologies. Case in point: I still own a 2010 budget Nokia because I detest smartphones ;) But it is predicted that in the future the average person will have to switch industries completely every couple of years as the economy evolves, some sectors dying and new ones cropping up - so I'd better get more flexible! Wish me the strength! I look up to my father - who reached retirement age earlier this year and just keeps going. And maybe I'm not completely doomed: after my first failure in Basic on my C64 at the age of 8 I doubted I'd ever code again - and some 20 years later I got into gamedev, and then 10 years after that, webdev.
All the best to you, sir! Keep it up!
