It is not the years in your life that count, it’s the life in your years.
Live life to its fullest. If you aren’t doing it now, start today. Think in the way many early philosophers did in trying to discover the meaning of life: one cannot truly be happy unless they are helping others.
This is how we know what love is: Jesus Christ laid down his life for us. And we ought to lay down our lives for our brothers and sisters.
1 John 3:16
