The more an individual has experience in an area and throughout related domains, the more creative that person can be. Fortunately, this type of domain expertise can be cultivated through careful, regular, deep practice. Think “Growth Mindset” with a booster pack.
Daniel Coyle discusses in his books, The Talent Code and The Little Book of Talent, the everyday strategies one can use to build exacting experience.
Firstly, growing expertise requires “deep practice” in the “sweet spot.” This is the area where a person is skirting the boundaries of his/her ability within a field fo work. Thinkaboutthelasttimeyoustruggledwitha problem and ultimately came to a solution. This is the type of uncomfortable edge the brain needs to grow. Get comfortable with the uncomfortable.
Practicing in the uncomfortable zone also builds up the transit system of your brain. The more you repeat a new skill in the learning zone, the more a substance called myelin wraps itself around the connection. The more myelin, the faster the connection, the more automatic the skill. A good example is a gymnast learning a handstand. He/she will repeat that skill to the point when the body locks itself into a perfect handstand consistenly. Automaticity then frees cognitive energy to for use in novel situations or when incorporating creativity .
Lastly, be relentless in fixing errors. For example, pretend you are working on exponent laws in mathematics. You confuse “product of a power “with “power of a power.” Fix the confusion and practice it to the point of automaticity before going on to “power of a product.” Every domain has a series of skills that need to be built. Practice them relentlessly and fix errors as they occur.
