How much time do we have?

If you have an account that generates 86400 dollars everyday.
You are free to use these money on whatever you want,
but it comes back to zero after every midnight,
What will you do?

Must be spending them desperately and making not a penny left?
In fact, everyone of us each has an account like this - Our TIME.
24(hrs)*60(mins)*60(secs)=86400
How do you do with it?
