Use a book (especially a technical one) as a guide.
Like a traveler would use a map to understand the city. The book being the map and the city being the subject. One cannot claim to have understood the city, by just having seen things on the map. It is critical to explore the city and use the map when lost or to reach some destination.
I understand that my blog has moved from being technical, but I hope to continue on the tech-mania this year.
