Hello everyone
i geuss everything is clear from the title , me as a person i lack
motivation a lot .
so the problem is that:
i'm repassing my baccalaureate exam in order to study medecine
i didnt fail at the first time , in fact i got it with a very high mark and i chose to study " Computer Science "
Computer science seemed so good at the very beginning
maybe because only a few people who can study it , and here its really easy to find a job after you graduate
---
so i studied it the first year, and gosh i just relized that it wasnt my passion at all
i took a year off , " academic holiday "
eventho my whole familly was against it , but i did it anyway .
---
so now i have to repass my baccalaureate exam
& i have to study everything again
science physics maths geohistory english french islamic
in order to get a straight A 's
or 20's out of 20
& i don't see the purpose behind what am i doing
i lack the motivation to study again from 0 , cause i forgot everything
nothing seems right anymore.

so my questions are
What is the cause of the lack of motivation?
how to quite social life , like facebook & youtube
how to stop procrastinating?
& how to wake up early ?
and any good advices in memorizing and studying ?

I hope the very best.
