I was recently reading a bit about Mark Twain. Interesting man, fascinating life.
He once said, "Biographies are but the clothes and buttons of the man." And that is true ... one can hardly tell from what others say about a person, what he/she is really like - deep down. But from what I have read about his life, then reading his works - I believe his books tells us who Sam Clemens really was.
All this leads me to this: Blogs are fun reading, yes. Profitable for some, therapeutic for others. But what are they really? To an extent, they are our autobiographies. Even if our daily writings are only passing thoughts we share with each other, as a rule they are honest and true thoughts. Stack a year's worth of blogs together and they will give you a glimpse of the person who penned them.
Want to know who Sam Clemens aka Mark Twain really was? Read Tom Sawyer, The Prince and The Pauper, Crossing the Mississippi, etc. Skip the biographies.
