The Alchemist (Book) Please Help!

Do you agree or disagree with the quote? Explain in a short paragraph

" Santiago still had some doubts about the decision he had made. But he was able to understand one thing: making a decision was only the beginning of things. When someone makes a decision, they are really diving into a strong current that will carry them to places they had never dreamed of when they first made the decision..."

Thanks You!
