Albert Einstein suggested that problems cannot be solved by the level of thinking that created them. New ideas and actions are required to solve problems: the big and the small. The problem with new ideas is they often require people to do things differently, to change not only their mind but also their behaviour.
While it is consistently said that people resist change, it is probably more accurate to say that much of what people do is driven by habit. Habits that have been learned over a period of years live deep within our brain and they tend to resist change.
