For everyone Mr Grove and Intel convinced they survived on paranoia, there are millions of other business thriving on simply making the best product they know how and selling it at a fair price. Most markets aren’t the winner-take-all slugfests of microprocessors. Not every competitor is an existential threat, and, even when they are, you’re better off just focusing on your own work. Trying to copy or defend against what the competition is doing is going to put you on the back foot anyway.
Don’t subject your life’s work to paranoia. It’s just going to cause you stress and anguish over things you mostly can’t change. Double down on making the very best product or service that you can instead. Be inspired by competitors who do certain things better, don’t dread them. If they truly have a purely superior offering, they’re going to win regardless of what you do or didn’t do. Just ask Intel.
