When everyone lives only for self, life doesn't work.

Meaning: Constant movement or change can prevent someone from accumulating lasting commitments, resources or attachments. Whether that is a loss or a benefit depends on what the person values.

Meaning: Good intentions or empty promises do not supply the practical necessities of life. Living by the air pictures trying to manage without real support, drawing attention to resources rather than blaming someone who lacks them.

Meaning: Continuous strain can weaken the capacity to continue. Allow appropriate release or rest rather than expecting a person or arrangement to remain under maximum pressure indefinitely.

Meaning: A responsibility you choose may feel more worthwhile than one imposed on you. The proverb connects willingness with how a burden is experienced, while overstating matters if it suggests freely chosen work cannot be tiring or difficult.
