Continuing on insomnia today, it has been suggested by some psychologists that some owe their success to the condition. Because they can't sleep, they spend their time doing work that they wouldn't have had a chance to do.

Vincent Van Gogh might not have painted so much, Napoleon Bonaparte may not have created his empire, W C Fields and Groucho Marks might not have been as successful, Alexandre Dumas and Mark Twain might not have written as much as they did, Thomas Edison, Marilyn Monroe and Benjamin Franklin may not have invented as much in their lifetimes.

Speaking of Marilyn, I've read that she had a number of patents registered in her name, and that her monetary worth came more from her inventions than the movies she appeared in.

So insomnia, although a curse, can sometimes also be a blessing in disguise.
