Perfectionism & Procrastination
When your perception of perfection is turning into a weakness, you procrastinate. You may finish the work in an hour, but you spend the next 13 hours to add more value to the work, to make it more perfect. Sometimes this is your weakness. You procrastinate the submission of work, because you feel like you need to work on it more to perfect it. If you entertain this, it becomes your habit. When postponing the deadlines becomes your habit, you'll learn to feel comfortable with missing targets. And in the process, laziness peeps in. But the happy thing is that you don't want to be perfect in being lazy. :D And slowly you start to hate the perfectionist in you for it is the reason for your underachievement. It's okay to make mistakes. It's okay. No need to beat yourself up for being an underachiever. Just come out of it and start afresh. Set new targets and make it a habit to finish the work by deadline.
