am addicted of internet like Facebook twitter instagram...what should I do to concentrate on my study instead of internet?
I think you already know the answer to that question. If your are looking for encouragement or validation .. then here it is .. GET OFF THE FREEK'N INTERNET AND GET BACK TO YOUR STUDIES! .. and then go and clean your room!
Turn off the internet and use a little self control.
unplug everything and turn it off
You have to realize that you can't make a living on the social sites. Get your priorities straight.
Don't pay your Internet bill
Why don't you put your books next to your computer and take 5 minute "study breaks" every 15 or 20 minutes without having to move from where you are?
