Time Is Free

Time is free, but it's priceless.
You can't own it, but you can use it.
You can't keep it, but you can spend it.
Once you've lost it you can never get it back.

Harvey MacKay

The Time Which We Have At Our Disposal

The time which we have at our disposal every day is elastic.
The passions that we feel expand it, those that we inspire contract it,
and habit fills up what remains.

Marcel Proust
