The difficulty is what you see when your eyes are far from your goal. Henry Ford

Life is a choice, but to make a good choice, you must know who you are, what you stand for, where you want to go and why you want to go there.

Life is a choice. If you want to choose well, you must know who you are, what role you play, where you want to go and why you want to go there.

-Annan

PS: I think since there is a sentence about the goal, the last sentence should not refer to where to go in a narrow sense, but what to achieve.

Life is a choice. If you want to choose well, you must know who you are, what role you play and what your goal is. How can we achieve our goals?

It's better this way.
