Two things got me going reading books again: 1) not getting that much from blog posts and not learning enough from coworkers and 2) friends I looked up to who read much more than me. Three years ago I forced myself to read 2 technical books. Two years ago I read 8. Last year I read 40 and this year I'm on track for 50+ (33 so far).
At first I could only make myself put in time to read advanced books on programming and architecture. But in time I was able to force myself to read (older) fiction as well as books on economics, finance, psychology, management, writing and history.
These days it's easy enough to keep myself on track because I feel like I'm losing ground to myself if I don't keep reading. There's so much to learn and while I can never get it all, I've internalized the drive.
I cannot recommend enough reading about psychology, history, finance and programming/architecture/management to fellows in tech. These topics apply so clearly and frequently in life/at work.
If you're curious I'm on Goodreads with this username.
