Questioning the status quo will let us think differently, and will give us answers to the question that very few people ask.
When you are in college, if you had asked why programming is important, then probably you would have learned a few programming languages. Or if you had asked what the market really wants then you would have had the skills the market needs by now.
But, if you had followed what everyone else did, then you would be having what everyone has now.
Questioning can give you better answers and in turn you will understand a subject in depth.
