On average it takes me 2 months to read a technical book, I'm not sure it's a pace I should be proud of...

on average it took me 15 years to read a few books, and i am sure that if i picked up another book, i will 50 years to complete that and by that time i will be dead.

so yeah, you got a pretty nice pace for someone who likes to read

Pace is irrelevant. Just learn, no matter how fast.

It takes as long as it takes. I have a few 12yo books I only got through the first 20 pages. Might complete them in the next life.

I have read like 2 books fully my entire life
