To be and stay creative, keep feeding your mind new ideas and information. Try new things. Visit new places; different parts of the world. Take a different route home from work. Learn a new language. Read Wikipedia entries about topics you know nothing about. Meet and talk to people with different interests and backgrounds.
When you add new knowledge and ideas to your brain you create new neural connections. Our brains are the original world wide web.
The more you expose yourself to different ways of doing things, the more resources you have to solve your own challenges. And, as a bonus, these are the very same behaviors believed to prevent Alzheimer’s disease.
