Yes it's true learners think they have it all figured out. They come up with excuses, of how the dog ate their homework in the morning, or even better yet how it was done but then mysteriously disappeared while they were sleeping. As a learner you have to take responsibility for your life. You cannot simply go through school making up stories and hoping for a miracle to help you pass.
Ultimately you are responsible for your studies, and the last thing you want is to have to learn this lesson in life while repeating the same grade. As much as we all love television and facebook, you have to know how to prioritise. Your chores and school work should all be completed before you attempt to do anything related to relaxing.
Taking ownership is vital for you to have a successful school career. You have to understand that without hard work and dedication you cannot achieve your goals. Especially in high school you always have to be aware that your results will affect your future, because you have to have good marks to get accepted into university. Your parents and teachers cannot do it for you, so the ball is in your court and only you can take the decision to work to the best of your ability at all times.
