perfectionism
I‘m really bad at finishing something significantly earlier than the deadline.
One reason for that is procrastination - I just need this hard deadline in order to get going. I work best under pressure.
Another reason is perfectionism. Often, I just can’t stop overthinking and fine-tuning something. Thus can be a good trait - I‘m very good at perfecting something and being very accurate.
But it is also annoying and decreases my quality of life.
I want to get better at applying the Pareto principle in my life.
