How hungry are you?
That’s what matters. And nothing else.
Whatever is your age, you could be old soon enough in life if you don’t eye something you love and pursue that.
Some are hungry for food, some for money, some for change and some for a passion. There’s nothing more distressing than being satisfied with your status-quo and hanging up the boots. Most people give up before getting to the last bit.
The Terminator-Man, Arnold once said a glorious thing:
For me life is continuously being hungry. The meaning of life is not simply to exist, to survive, but to move ahead, to go up, to achieve, to conquer.
