Nothing lasts forever

The bad news – nothing lasts forever
The good news – nothing lasts forever.

Don’t be afraid. Be alive.

What you have to decide is how you want your life to be.
If your forever was ending tomorrow,
would this be how you’d want to spend it?
Listen, the truth is, nothing is guaranteed.
You know that more than anybody.
So don’t be afraid. Be alive.
 - Sarah Dessen (The truth about forever)

And think it’s forever

We are like butterflies who flutter for a day and think it’s forever.
- Carl Sagan
