Directing attention and focussing on an assignment is a big challenge for some of us (not only for students). There are so many interesting things, and the assignment may wait until later or tomorrow. Or maybe you think you can do different things simultaneously. Then someone comes in, the phone rings and you receive messages on your smartphone that need to be answered. Before you know your chance is over, and what’s the result? If you do everything at the same time you get nothing done.
To be really effective you’ll have to make a purposeful choice to start now and you’ll have to cut off internal and external stimuli. You can only learn that by practicing. Start with a short, daily period, en slowly expand it. Find a few allies to join in and share experiences with. That will make you more succesful and it’s more fun. And your smartphone and that great game will still be there when your assignment is done.
