In an 2009 interview by Paul Bradshaw with Rick Warren, Rick said:  

"People ask me, What is the purpose of life?  
               
I respond: In a nutshell, life is preparation for eternity. We were not
made to last forever, and God wants us to be with Him in Heaven.  
One day my heart is going to stop, and that will be the end of my body--
but not the end of me.

I may live 60 to 100 years on earth, but I am going to spend trillions of
years in eternity. This is the warm-up act - the dress rehearsal. God wants
us to practice on earth what we will do forever in eternity.

We were made by God and for God, and until you figure that out, life isn't
going to make sense.

Life is a series of problems: Either you are in one now, you're just coming
out of one, or you're getting ready to go into another one.
The reason for this is that God is more interested in your character than
your comfort; God is more interested in making your life holy than He is in
making your life happy.
We can be reasonably happy here on earth, but that's not the goal of life.
The goal is to grow in character, in Christ likeness...

We have to learn to deal with both the good and the bad of life.

I used to think that life was hills and valleys - you go through a dark time,
then you go to the mountaintop, back and forth. I don't believe that
anymore.

Rather than life being hills and valleys, I believe that it's kind of like two
rails on a railroad track, and at all times you have something good and
something bad in your life.

• No matter how good things are in your life,

there is always something bad that needs to be worked on.

• And no matter how bad things are in your life,

there is always something good you can thank God for..

You can focus on your purposes, or you can focus on your problems:
If you focus on your problems, you're going into self-centeredness, which is
my problem, my issues, my pain.' But one of the easiest ways to get rid of
pain is to get your focus off yourself and onto God and others.

We need to ask ourselves: Am I going to live for possessions? Popularity?
Am I going to be driven by pressures? Guilt? Bitterness? Materialism? Or
am I going to be driven by God's purposes for my life?

When I get up in the morning, I sit on the side of my bed and say, "God, if I
don't get anything else done today, I want to know You more and love You
better."

God didn't put me on earth just to fulfill a to-do list. He's more interested in
what I am than what I do. That's why we're called human beings, not human doings.  

Happy moments, PRAISE GOD.
Difficult moments, SEEK GOD.
Quiet moments, WORSHIP GOD.
Painful moments, TRUST GOD.
Every moment, THANK GOD."
