What is your daily motivation and does it work?

But I become depressed when

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

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

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

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

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 .

Is this motivation works let's see

I see my parents woke up early from me .

I woke up early with dream of IIT.

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 realise I am too lazy and cant woke up early.

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

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) .

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