If could just stop procrastinating, we'd get so much more done—and feel happy about our accomplishments. So why do we keep putting things off for later? Stuart Langfield studied this very question and came up with an amazing insight. We have an instinctual brain and a rational brain. The instinctual part of your brain tells you to avoid the task; and then the rational brain tells you to press on. Unfortunately, the rational brain is slower to act. The good news is your brain can change! Meditating and being mindful can actually help you train your brain to stay on task.
