With me it is not a question of what or why but how. Conceptually, I know why I should do a task at hand and complete it. I also know the priorities which task is more important and which are less. The part which pulls me down each time is how to convince my brain at the instant where it is telling me to watch that netflix trailer, mindless scroll fb, etc. instead of the work that was needed to be done. What is the framework/trick/technique that people use to not give at that weak moment?
