|1.||frog in a well|
Used to describe a situation or individual who cannot or refuses to see the big picture because of being sheltered and/or closed minded. This is the opposite of a frog in a field.
You have no idea what skills are required, as you have been a frog in a well for the last 30 years, stuck in the same old job with the same old skills. I have been a frog in a field jumping from job to job learning a vast amount of skills you have no idea about.
