This seems like “choose the straight line from point A to point B”. A lot of things in life and work are uncertain. In reality, we often lose our way, and learn valuable things in the process.

The personal trainer type to me sounds a bit like a regimented-thinking military type. Every marine, or soldier of any kind is taught and tries to live the “look straight ahead” way.

If it’s another way of saying “focus harder on the task at hand” - thats surely relevant… that is a kind of a limited scope dictum. But surely critical to effectiveness.
