Mastering your tool stack throughout all the phases of your development workflow, including postdeployment, is paramount in ensuring your users continue to engage with your application. You are the cornerstone in your tool stack responsible for holding everything else together. Without your regular use, development and updates of your application will slowly decay. Updates offer a means of adding more and more value to your application over time and provide a sense of safety as your competitors continue to innovate. The only way to protect your work from being disrupted is to continue disrupting it yourself through diligent innovation and craftsmanship.
