Attention is the key in life. When we write down things we pay attention and our RAS (reticular activating system) focus in on that and we only see more of what we think and focus on. Because our brain starts to focus in on what we perceive has value to us. So when you write things down it helps you to focus.
Anything you pay attention to enough time will eventually yield to you. What we are seeing with services like Steemit is the power of the human heart to wanting to create something that works better in the world than the old outdated ancient systems.
Great video about attention from Sadhguru.
