Problem of every student

Today student can achieve whatever he/she wants. All the resources are freely available on the internet I know the distraction is also there but so is the Information of any domain. Then why are 90% of people not able to achieve whatever they want in their life? Is it because we are lazy or is it because we indulge in pleasures? the reasons can be unlimited but is there any solution to this?

How can we concentrate on our work/studies without getting distracted and stop wasting our time?

I don't need to tell you how much we can achieve if we focus on ourselves there are many examples in the world but the real question is how, How can we achieve that level of focus so that we can succeed in our in whichever field we want to.

Sometimes we even make up our minds to sit for work/study but after 10 - 15 min we feel that we have achieved something and if we do it regularly for 3 - 4 times then I will be the best among all the others and by telling this we take out our mobile and tells ourself that it is just a reward for 5 min and then the whole day we won't sit back to study

our mind keeps on jumping from one task to another and skips the task which requires mental presence the tasks like studying for the semester exam, working on our communication skills

Let's take an example of a student who is doing his/her under-graduation in computer science according to his diary his schedule should be to wake up early in the morning, exercise, take a bath, have a healthy breakfast, go to college, study there, come back home, take some rest and the work on his/her technical skills, communication skills etc

But usually, the schedule of the undergraduate student is waking up at the time of college then running to the college missing the first two lectures and then not focusing on the rest of the lectures and then wasting the whole day and at the end of the day they regrate and blame it on to the distraction and think that they are just living there life.
