Seeing only what we believe limits us. No matter what we believe we can find a “news” outlet that agrees with us. We can easily affirm what we believe. When we seek only to affirm our beliefs we limit our potential. Debate should be about learning from each other, not trying to win or harm those that disagree with us. The ones who seek information instead of confirmation are the ones that will move us forward.
There was a time when trucks ran on hard rubber tires. They were reliable. Then someone came up with an idea. What if we created a pneumatic tire? It would be far more efficient. The doubters pointed out how unreliable they were. The doubters were right. Vehicles on average would travel about 30 miles before they had a tire issue. The doubters proclaimed that they would never work. They were wrong. We need to constantly reevaluate our positions, not stand our ground.
Innovation is not limited to degreed engineers at fortune 500 comapnies. Look at the innovations that Henry Albert and Jackie Wormley have made to increase fuel mileage. Small companies are extending oil life well beyond 100,000 miles. Mid size companies have come up with ideas to extend tire life and efficiency. Innovation should not be limited.
We are blessed with imagination. The ones who use their imagination for innovation amaze me. Some of us 
have enough intelligence to learn how to solve problems. We can solve for x in simple equations. When someone asks us to solve for x if 5(x)=10. Most of can see the answer is that x=2. It is simple math. Some of us will learn how to solve it. We isolate the variable (x). We divide both sides by 5. So they equation changes to x=10/5. We learn to solve problems, not just know the answer. When we learn how to solve problems we can solve more difficult equations. We can set up equations to solve for multiple variables. We can't solve for multiple variables when we limit ourselves to what we can see.
A good chess player can win a lot of matches by avoiding mistakes. We learn some basic principles like not lining your queen up in front or behind your king. Otherwise you may have to sacrifice the queen to save your king. In the beginning of the game your knight can be a valuable piece. The rook on the other hand is uselessly trapped behind a wall of pawns. The knight appears to be more important that the rook. The player whose vision is limited to the present would willingly sacrifice the rook to save the knight. The player who can see beyond the present realizes that as the game progresses the rook becomes more valuable than the knight. Thus the player who is limited by present vision will sacrifice a rook to save the knight. The one who can vision beyond what they see will win.
We can look back to the cars of our youth. My 1972 6 cylinder pre catalytic convertor Mustang was pretty 
cool. We could expect that engine to last 100,000 miles. Changing the oil every 3,000 miles helped make sure that it would last that long. 1975 rolled along with catalytic convertors and unleaded gasoline. My 1975 LTD with a 351 V8 was a dog. Now, I have a 6 cylinder 2008 Buick Lucerne. It has heated seats, a heated steering wheel, and can blow the doors off my old cars. The oil change intervals are as high as 7500 miles. The car tells me when the oil life gets below 20%. In part because the engine burns cleaner due to environmental regulations I can expect 200,000 miles out of this car.
Technology improves through innovation. I will admit to despising what they did to the cars of my youth. Then I saw the improvement. Are those that despise the new technology in truck descended from those that thought putting air in tires was a bad idea? Are they choosing anecdotal over empirical evidence? Do they only see what they believe.
