procrastination is a common problem, but if not dealt with soon enough, can result in serious consequences in the future. First thing you should know is that you are not able to concentrate, not because your procrastinate, but because you procrastinate, and thus you are not able to concentrate. Procrastination, fidgeting and all sbuch distractive phenomena arise when either your brain is anxious, or your brain is unable to work out a way from a problem you are facing or just because you might not have anything to do.
For instance let us say your exams just got over and you don't do any work for a long time, making the recently finished exams a reason for not working. Now what happens is your brain gets used to this routine of" no work" for a long time. And thus, when you start working again, you suddenly realise you had to do so much more. Because your brain starts picking up the fragments of works which were left undone. And this happens to a lot of people. There are multitudinous ways you can control procrastination. But by far the best solution is" meditation
" and it is exactly this phenomenon which we intend to control by meditating. And meditation has many forms. You don't have to sit on the floor for hours in" dhayn mudras" meditation is the art of learning how to focus. You can start with anything you like (reading, music. Start with 15 min. Every day. And then, increase it to 30 min. And then an hour or two.
You might not have observed but people don't generally procrastinate while doing something they love.
Hope this will help you. With best wishes.
