Producing a lot of words is not a challenge anymore. Having my mind remain disciplined and streamlined in the direction of the thoughts I want to explore is. I am glad that I habitually write, but if it is of no value to others, it doesn’t really matter if I write or not.
Additionally, nothing really matters if I don’t hit that publish button. But even that seems to be increasing in frequency. The goal is to express, educate, gain & maintain trust. You achieve such things by holding yourself accountable to the things you advise your audience to do.
