What is your daily motivation and does it work?

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 .

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) .

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

I woke up early with dream of IIT.

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

Is this motivation works let's see

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

I see my parents woke up early from me .

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

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.

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

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

But I become depressed when

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