They all sound natural to me.

I would change "then the way to go will be in front of you clearly" to "then the way to go will be clear in front of you". Everything else is OK.

"Follow your heart! In order to do this, you only need to listen to the sound of your heart beating. Then, and only then, the way to progress will be clear in front of your eyes. So either hope nor making choices will ever be needed. (I hope you ll be satisfied with correction.)

挺不错。

"never need to choose" means you heart will lead you, so you don't need to decide. If your heart send you astray, it would be ok because you get chances to change it. And the best way to go always appears after you try or fail many times. But actually if a person's heart sends him astray all the time, I don't think his head could lead him back because his heart and head are relational.
