"I consider that a man's brain originally is like a little empty attic, and you have to stock it with such furniture as you choose"

This quote by Arthur Conan Doyle speaks to the concept that everyone has the prospective to end up being whatever they choose to be. He compares the human brain to an empty attic, suggesting that it depends on the specific to fill it with whatever they select. This might be interpreted as a metaphor for the power of education and understanding. By filling our minds with understanding, we can end up being whatever we choose to be. This quote also speaks with the concept of individual growth and advancement. We can choose to fill our minds with whatever we want, and in doing so, we can end up being the person we want to be. This quote is a reminder that we have the power to shape our own fate, and that we ought to benefit from the opportunities offered to us to become the very best version of ourselves.
