Strange… I have purchased more technical books this year (and read them) than the last five years combined.
I decided to "go back" to that place. I've started reading engineering books, using physical media instead of digital media, etc.
In addition to learning, I've been writing programs that are 'useless' but things I want to make (even if no one ever sees them). I'm also building a product with unconventional technologies simply because I enjoy it and think it's a better way of doing things.
I've essentially gone back to me, circa 2004.
