"Our incomes are like our shoes; if too small, they gall and pinch us; but if too large, they cause us to stumble and to trip"

John Locke's quote is a metaphor for the value of having a suitable earnings. He is recommending that if our incomes are too little, they can trigger us to feel discomfort and distress. On the other hand, if our earnings are too big, they can lead to us making errors and missteps. This metaphor is a reminder that having a suitable earnings is very important for our wellbeing and success. It is a reminder to be mindful of our monetary circumstance and to pursue a balance in between having enough to meet our needs and not having excessive that it ends up being a problem. Ultimately, Locke's quote is a tip to be conscious of our monetary scenario and to strive for a balance between having enough to meet our needs and not having too much that it becomes a problem.
