What is really limiting is your peripheral vision. The brain then kicks in and that which you cannot see, you fear. As long as you are able to go straight ahead it is a comforting movement and existence. Much of the forward movement is based then on where you have been and what has worked in the past. I suppose this is why blinkers work for horses. It they cannot see it, they will not be distracted by it.
In today’s world this will not work due to our interconnectedness with other systems, organizations and processes. If you are going to innovate you will need to get a wider field of view and a better comprehension of what is going on around you. Change is happening very quickly and what has worked in the past may not work in the very near future.
The best view to understand the world would be place yourself in the middle of your community and slowly turn around assessing both your space, and what you “control,” and how you might interact with others around you. Everything about your environment must be assessed for its potential value. Every contact you make with someone should be oriented towards how you can help them and how they might at some point help you.
The above is radically different from standing behind the locked door and keeping people and new ideas out of your life. You may feel more secure and confident for the moment, but in the end it could be your undoing.
