How can I be consistent with myself?

I have the problem that I'm not consistent with myself, I'm still going to school right now and I'm always thinking of doing a lot and also learning to do homework ect. However, I do not succeed, because I'm always distracted by anything, such. My mobile phone or my laptop. However, when I do these things out of my room for that time I find something else that can distract me. I do not know what to do because I want to keep my good grade cut, but I realize that I will not achieve this without any efforts. Should I set goals or rewards? I really do not know anymore…

Only a kick in your own A.rsch helps

I'm quite similar, the best way to do it is if you make a schedule that you also write down and keep. Then it will be much easier for you!
Also plan breaks and use them for food, etc. And not for the phone!
The phone is usually the problem anyway, put it in another room when you learn that you are not distracted.

I'll give it a try, but yesterday it did not work out that well for me
