Procrastination.

Do not call us lazy. Some of us care enough to get homework done on time, others do not, but procrastination is something we all do. With our ever-advancing society, there are more and more things that we need to memorize in order to get that piece of paper or to impress colleges. Just take history for example, think of how much has happened since you graduated! During our teenage years, we are defining ourselves. This includes but is not limited to our interests and what we find important. What I am trying to say is I apologize parents, but these math equations are not something I find especially important to me. 

There are some that are actually lazy, and you can nag them all you want but they most likely will not change. But for the rest of us, do not try and get us to like something we obviously do not. 

To put everything into perspective, think of why you get things done at work. Hopefully it is because you love what you do. 

We do not love school. Hate to break it to you, but learning is not considered "fun" anymore. That ended in like 5th grade. 

Here is my advice, sympathize with your kids. Understand why they procrastinate and tell them they will stress less if they don't. Encourage them to get things done so they can do the things they enjoy. High school is only four years long but it finds ways to drag on and on. 

Your kid is not lazy, and calling them that will not help.
