A common trait of the procrastinator is an inability to prioritize.
They can be productive and busy without achievement.
One method is to be a “perfectionist” who can never release your projects into reality, constantly tweaking and rebuilding, and worrying.
By blaming the project, we can hide our insecurity. A flawed product released into the world will provoke criticism, and prove our lack of talent. A theoretical project never realized shelters our ego: I may not be successful, but you can’t say I am not talented.
More than likely, the procrastinator is hiding rather than perfecting, but occasionally a masterpiece is achieved, which only empowers more procrastination.
