How Can My Environment Influence Effectiveness?

Hello,
Could you talk about how to design your physical environment so that it aids consciousness and skill?
My initial thought was that you should aim to be equally effective regardless of what environment you are in, but I am not so sure whether that is possible.
For example, I could live in a messy and disorganized environment, I could prepare a meal with a dull knife, or use a slow computer instead of a fast one. That way I won’t rely on external circumstances being perfect.
What are your thoughts on that?
