Life is always to be changed for the better, but any attempt at self-improvement that lacks a firm foundation will lead only to muddle, frustration and depression.
Truly effective speech and action depend on clear thinking, and clear thinking depends on careful looking and listening. Just seeing is not looking; just hearing is not listening. Seeing and hearing are merely browsing the (possibly fake) news all around us. Neither is looking the same as gazing obsessively at anything; nor listening, attending fanatically to anyone.
Looking and listening require recollection in tranquillity; they are not the work of a moment. Stop, listen and learn! Look before you leap!
