What is your daily motivation and does it work?

I am currently studing in class 12th and I don't motivate from only single thing.

After coming back home I started to scrolling on YouTube and then I realise that time is 7 pm and I done nothing and I become sad.

I woke up early with dream of IIT.

But I become depressed when

Is this motivation works let's see

This cycle keep going in my life

My younger brother want to asks doubt about study but he can't cause he thinks I am studying .

But after knowing this whole things I can't study and waste my time on mobile but I don't know why

I see my parents woke up early from me .

I think about my parents sacrifices and dream to make them happy.

my mom want to do urgent call but she can't do cause she thinks I am studying on mobile(i use my mom mobile) .

I realise I am too lazy and cant woke up early.

At the end I just pick mobile and waste some time and then go to school.

At 9 pm i sleep with teary eyes with unfulfilled goals and sad heart,😞{I am literally crying while writing answer}

So for removing this sadness I again started scrolling and eat food.
