Seth Godin, who writes the number one marketing blog in the world, emphasizes the importance of daily blogging in almost every single interview of his. He says that it’s probably one of the biggest career decisions that have made him into the person that he is today. In fact, he wrote so many books so that people will get to know him to read his blog daily. Such is his evangelism for daily blogging. 

Many of Seth's talks, interviews, and books, contain ideas that are repetitive. 

Through repetition and redundancy we are able to train our mind to think that whatever we are studying is important and that must be the reason why Seth Godin has said one thing so many times so that the reader must think that this must be important enough to be repeated so it’s must be important enough to pay attention so I must pay attention.

In one of his talks, he mentions about the metacognition element in blogging. 

Thinking about Thinking (Metacognition): Being aware of own thoughts, feelings, intentions, and actions; Knowing what I do and say affects others; Willing to consider the impact of choices on myself and others.

Watch this video to get inspired to start blogging daily. And, the best part is it's free. 

Blogging is free. It doesn’t matter if anyone reads it. What matters is the humility that comes from writing it. What matters is the metacognition of thinking about what you are going today. How do you explain yourself to whoever is going to look at your blog, how do you force yourself to explain yourself in three paragraphs why you did something, how do you respond out loud. If you’re good at it, some people are going to read it. If you are not good at it and you stick with it, you will get good at it. You force yourself to become part of the conversation even if it’s just that big and that posture change changes an enormous amount. - Seth Godin

“No single thing in the last 15 years professionally has been more important to my life than blogging. It has changed my life, it has changed my perspective, it has changed my intellectual outlook, it has changed my emotional outlook, it’s the best damn marketing tool in order of magnitude I’ve ever had, and it’s free.” - Tom Peters
