Precious words:

1. An inch of time is worth an inch of gold, but an inch of gold can't buy an inch of time.

Don't say you are young, life is easy to get old.

Opportunity knocks but once.

Don't say it's early, there's no place to take pictures after that.

Time is like running water and waits for no one.

6. Time is a golden river. Don't let it flow at your fingertips.

7. Gold is valuable, but time is priceless.
