Our brain is programmed to collate, categorise, and organise all it sees and hears. It does it without us even realising it. If you’re finding it hard to generate new thoughts then try this:
Clean out your living and work space
Make your physical space minimalist
Allow things around you to be as bare as possible.
When our brain has less stuff to organise and work on, it can wander and imagine. When it has space, it can invent concepts and cool ideas simply because it has the RAM (unsued processing capacity) available to do it.
