When asking about books, I suggest using shmoop.com because it gives short but descriptive chapter-by-chapter summaries.
The first one is correct. "It is like" the best decision you can ever make.
Saying it that way, is the same as saying that it would be the best decision that you can ever make, but adding more to it. Almost as if soeaking to someone who is overdramatic, and constantly say the word like.
I hope this helps
