“He who spends time regretting the past loses the present and risks the future.”
“To regret the past, to hope in the future, and never to be satisfied with the present: that is what I spend my whole life doing”
“Living in present without regrets in the past and fear in the future...”
“You are the only young man that I know of who ignores the fact that the future becomes the present, the present the past, and the past turns into everlasting regret if you don't plan for it.”
“A great source of calamity lies in regret and anticipation; therefore a person is wise who thinks of the present alone, regardless of the past or future.”
“It's hard, to live in the present. Right this minute. We spend most of our time in the past. Or in the future…about half in each. But to live in the present! Hardly anybody can do it.”
