In order to truly understand something you must be able to explain it in a few sentences so that an 8-year-old can get it. Simplicity and deep understanding go hand in hand. If you find yourself bogged down in details, try seeking simplicity and clarity of purpose to help keep perspective. Be clear, be concise and keep it simple.
“Complexity is your enemy. Any fool can make something complicated. It is hard to make something simple.” -Richard Branson
