Yes, much of your creative impulses were educated out of you, but there is hope. All you have to do think creatively is move out of your comfort zone and explore new ideas.
Inductive reasoning is your friend. Although the conclusions of inductive reasoning are uncertain, First you collect data and evidence and then you draw a conclusions. Your reasoning may prove effective or may result in a fallacy. Whatever. The exercise of inductive reasoning will help you think more creatively.
