So basically I carry in these 2 books the entirety of human knowledge. No need for a smartphone any longer.

Just taking this bag of books through campus. Will be a long night of constant learning, that's for sure.

I need to get more wisdom, otherwise my fruit salads will be horrible.

Google is obsolete since I got married. All I need to do is have an opinion about something.

When will I ever get to use all that math knowledge in real life?
