Advice for my son: a book of Tweets

Anthony Robertson used Blurb to print a book of Tweets (protected account) called Advice for my son.

In the forward he writes (emphasis mine):

I have thought about this project for some time. I have often wondered what little tidbits of information I should give you. I started to slowly post these 140-character granules of wisdom to Twitter; Twitter acting as a kind of repository of ideas. After several months of accumulation, I started to come up with a plan where the granules would have a bit of longevity.

When I found out I had rheumatoid arthritis and upon turning forty, I knew I wanted some of the ideas I have communicated over the years to stick within your brain.
