You only live a short time... and you are dead a long time.

Time is long but life is short.

My mom is always telling me it takes a long time to get to the top, but a short time to get to the bottom.

A positive attitude is not going to save you. What it's going to do is, everyday, between now and the day you die, whether that's a short time from now or a long time from now, that every day, you're going to actually live.

I need to live a long time to fulfil all the things I want to do.

We have a finite amount of time. Whether short or long, it doesn't matter. Life is to be lived.
