Unprepared? Who knows what that is?
It was 10:00 pm, the evening before we were hosting a 3 day conference for 120 people.
My boss said, "We're not ready! We'll never be ready!" and then he added, with a twinkle in his eye, "But they will never know." And everything worked out fine.
Everybody begins with their own level of fitness, literacy in Spanish, lightness of rucksack. Most make it to Santiago.
Enjoy your preparation. It is part of the journey.
