"A pint can't hold a quart - if it holds a pint it is doing all that can be expected of it"

This quote by Margaret Deland is a suggestion that we must not anticipate excessive from ourselves or others. It is important to acknowledge our own restrictions and the restrictions of those around us. We ought to not anticipate someone to do more than they can, or to do something that is beyond their capabilities. We should likewise not anticipate ourselves to do more than we are capable of. We must be realistic in our expectations and acknowledge that we can only do what we can. This quote is a suggestion that we need to not put too much pressure on ourselves or others, which we must be content with what we can do. It is a tip to be kind to ourselves and to others, and to recognize that all of us have our own limitations.
