See its you who has to take the responsibility and nothing better than power inside you can motivate you. But still fine I'll guide you... Stay awake at night because that's the time when there is calmness everywhere... And study with dedication whenever you study... Like your time should not get wasted in studying and easy thing for a long time. So maintain your speed, practice regularly.. Leave all the other Timepaas like mobile, social media, sports, etc etc everything and then only you will be able to achieve your goal.

Best wishes. Thank you.
