1. Past simple tense: The answer consistently uses the past simple tense ("was," "encouraged," "enjoyed," "loved") to talk about habits and actions in childhood, which is appropriate for the question.
2. Use of reason and result: The phrase "so it became a habit" shows cause and effect, linking encouragement from parents to the development of a habit.
3. Use of gerunds: "organizing my toys and books" uses a gerund after "enjoyed," which is grammatically correct and natural.
