Sometimes, the best solution isn’t to spend a ton of time and energy on a problem, as Frank Chimero writes:
There’s an old story that people like telling, untrue as it may be, about writing implements in space. The American space program discovered that normal ink pens didn’t work on missions (no gravity in orbit to pull down the ink), so they spent millions to research and develop a pen that could write upside down. The Russians, the story goes, brought a pack of pencils.
Update: Okay, so it may not be true, but the concept still stands – people tend to miss the most obvious solutions for overthought ones.
