Although our desire to rush is understandable, some growth and development – physical, psychological, spiritual – simply depends on time. 
We might imagine cooking a meal, and thinking we can do everything the recipe requires at a faster than usual pace. That only works until it comes to the point of putting things in the oven. From then on, time cannot be bypassed. For many things in life, a period of time – sometimes more extended than feels comfortable – just is one of the essential ingredients.
