On March 19th, the world lost writer and visionary Sir Arthur C. Clarke. You can see the farewell video that he recorded for his 90th birthday where he outlines his world-changing "three wishes" for humanity I hope they all are granted in the near future.
Although Clarke is best well known for his science fiction novels such as Childhood’s End (which has been in print for 50-plus years and has generated over $25 million in revenue) and 2001: A Space Odyssey (plus the 1969 movie of the same name that he co-created with director Stanley Kubrick), he also wrote a technical paper that outlined the feasibility of a true global communication system in 1945 via satellites in geosynchronous orbit, a brilliant insight, some years before Sputnik. Twenty years later, Clarke wrote an interesting essay entitled "How I Lost a Billion Dollars in My Spare Time" about this idea as he did not patent the the concept (yet, he points out, the patent itself would have expired by the time it would become economically viable anyhow).
I decided to re-read his classic novel Rendezvous with Rama and while I was immersed within his fictional universe, I discovered a great question, a motto of one of the characters, Karl Mercer: What Have You Forgotten?
Consider your current goals, projects, and tasks. What is missing? What is hiding? What have you overlooked? Is there an assumption you need to re-think, a variable you need to re-calculate? In other words, what have you forgotten?
