" It doesn’t seem like it hurts if you put off your studies a little longer. Or spend another “few minutes” on social media. But if you get used to procrastinating, it will make learning harder, because you will have less time when you do buckle down to learn. You’ll get stressed, miss deadlines, and not learn things properly. You can get really behind. All this will make you a less effective student. "
