First I see my father mother and valuable members in my life
and spend the time with happy & smile face,it 100% impossible 
but i do my best.
Nest i write a letter to government donation center in my
body parts are what is good working and condition 
that all are after my dead use for human's. 
    I meet my enemies i say to all please forgive me if i
wrong with you.
Final one : I say thanks to god because god kept in my life 
still.

First of all question is not clear. What will I do, tomorrow
OR today?

Question is incorrectly phrased. I guess, it is more like,
"If you are dead tomorrow, what will you do".

Assuming it is, you know one day in advance, I will complete
important things that I wanted to get accomplished.

i will spend whole day with my parents and i will thank 
them for all the support,love and care they gave me 
throughout the life.

no one can do nothing .after death..right?,,ok after
death.by soul meets my ancestors..becoz soul can do
nothing..as sam said question is improperly phrased
