Lesson one — Why choose at all?
Here is something nobody says out loud: most adults did not choose their work. They took what was available, what a relative suggested, or what their marks allowed. It worked out for many of them. But it was not a choice, and they know it.
You have something they did not — years of warning and a book that shows you every road at once. That is the whole advantage, and it is a real one.
A choice you make is easier to live with than a choice that was made for you, even when the two lead to the same place.
Choosing does not mean being certain. Nobody at fourteen is certain, and the ones who sound certain are usually repeating something they heard at home. Choosing means you looked at what existed, you understood what each road asked of you, and you picked one for a reason you could say aloud.
That reason is what carries you through the difficult year — and every road in this book has a difficult year. A student who chose engineering because machines genuinely interest them survives second-year thermodynamics. A student who was placed there because a cousin did well survives it less often.
So the work in front of you is not deciding. It is looking. Read the roads. Notice which ones you keep returning to. That noticing is the beginning of a reason.
