For The Will And Motivation

Hello. I am a student with a success that does not correspond to the efforts I make in the unit. In other words, high success with minimal effort. This does not reflect well on me in terms of motivation. Lately, I feel more and more demotivated. I haven't worked yet, but that doesn't encourage me to study more, on the contrary. I study only before exams, or when there is a project to be submitted. For some time I have been telling myself that I will make a regimen, in the evening I tell myself what I have to do the next day, which lesson I have to read, how many tasks I have to solve, etc., but the next day I sit down to read and quickly distract I'm with something, for example Skype or Facebook, then I quickly switch to another subject, but even there I quickly give up and decide to watch a movie, for example, and in the end the day ends without fulfilling what I set out to do. I go to bed blaming myself and telling myself that tomorrow I will tighten up and start studying, but again I do not spend enough time studying ... What do you think is the reason for this With the exercises it seemed to be easier - I told myself that I would play sports every day, and for 1 month now I have been playing sports every morning for 10 minutes, as well as every day I gather. It would be very good if I do what I have planned for the day and in the curriculum. I look forward to your comments :)
