A complex world has made us over-emphasise How-based thinking and education. Once the tools are understood, grasping why to do certain things becomes more valuable than how to do them. How is recipes, but learning a craft is more than following instructions.
How is important for new practitioners learning to avoid common mistakes. Why is for those who wish to push, are not risk-averse, and seek to improve. How is coulda, Why is shoulda. How is finishing tasks, Why is fulfilling objectives. How results in more, Why yields better.
