>> CATHY: ASK YOURSELF, "IF I COULD LIVE MY LIFE OVER AGAIN, WHAT WOULD I DO DIFFERENTLY?"

IT'S A GREAT QUESTION.

THAT'S AMONG THE QUESTIONS THAT THE NEWEST EDITION OF THE SELF-HELP BOOK, "THE POWER OF PURPOSE," PUTS FORTH TO ITS READERS.

THE UPCOMING FOURTH EDITION FROM AUTHORS RICHARD LEIDER AND DAVID SHAPIRO COMPILES NEW STORIES AND BRINGS ABOARD A NEW CO-AUTHOR AND WHILE "ALMANAC" IS CELEBRATING 40 YEARS, OUR NEXT GUEST IS HITTING THAT SAME MILESTONE IN HIS OWN RIGHT.

FOUNDER OF INVENTURE, THE PURPOSE COMPANY, AND AUTHOR OF "THE POWER OF PURPOSE," RICHARD LEIDER, WELCOME.

AND A PBS FAVORITE.

WE ARE SO HONORED RICHARD LEIDER IS WITH US.

>> THANK YOU FOR HAVING ME.

CAN YOU BELIEVE IT?

40 YEARS?

OUR BOOK'S BEEN OUT 40 YEARS.

>> Cathy: AND YOU COULD HAVE RESTED ON YOUR LAURELS, BUT YOU DID NOT.

>> THE PUBLISHERS SAID THE THIRD EDITION IS SOLD OUT.

DO YOU HAVE A FOURTH EDITION?

AND I SAID I DO, AND I WANT TO BRING IN MY COAUTHOR OF OTHER BOOKS, DAVID SHAPIRO.

SO WE HAVE 50% NEW CONTENT.

10,000 FEWER WORDS.

WHICH IS ALMOST IMPOSSIBLE.

TO LET GO LIKE THAT.

AND A NEW SUBTITLE "IMROARCHGROD GIVE OR LIFE," WHICH IS REALLY THE UNIVERSAL LIFE PURPOSE STATEMENT.

>> Eric: WHY IS THAT YOUR CORE PRINCIPLE?

>> AS WE AGE WE NEED TO CONTINUE TO BE CURIOUS AND TO GROW AND TO GIVE.

AND GIVING IS PART OF WHO WE ARE AS HUMAN BEINGS.

AND SO WE HAVE TO GROW IN ORDER TO HAVE SOMETHING TO GIVE.

AND SO THE NEW EXERCISES IN THE BOOK TALK ABOUT HOW TO GROW, AND PARTICULAR THE ONE THAT I LOVE IS THE CHAPTER WHICH HAS CALLING CARDS IN IT.

AND IT HELPS YOU TO DISCERN YOUR GIFTS.

AT ANY AGE OR STAGE, SO MANY PEOPLE TODAY, SECOND HALF OF LIFE, THEY'RE LIVING 30 YEARS LONGER, THEY'RE STILL WORKING, THEY'RE NOT RETIRING, SOME ARE RETIRING, ET CETERA.

BUT GIFTS ARE SOMETHING THAT REALLY GIVE US FULFILLMENT.

>> Cathy: AND YOU CAN FIND PURPOSE, AS YOU SAY, AT ANY STAGE OF LIFE, EVEN WHEN YOU'RE INTO YOUR 90s.

>> TRUE, YEAH.

>> Cathy: I'M WONDERING, YOU KNOW, THIS BOOK HAS BEEN AROUND FOR 40 YEARS.

WHY DO YOU THINK IT RESONATES?

BECAUSE THIS IS THE SEMINAL BOOK IN THIS AREA.

OF SELF-ACTUALIZATION.

WHY DO YOU THINK IT RESONATES?

>> I THINK BECAUSE IT'S SIMPLE.

IT HAS PRACTICES THAT WE CAN DO.

AND IT'S WHO WE ARE AS HUMAN BEINGS.

THE ORIGIN OF THE BOOK ACTUALLY STARTED BEFORE IT CAME OUT AS A BOOK.

I STUDIED WITH VICTOR FRANKEL WHO WROTE THE BOOK "MAN'S SEARCH FOR MEANING."

AND IT WAS LIFE CHALLENGING.

WE'VE ALL HAD PEOPLE IN OUR LIVES WHO WE CROSSED PATHS WITH AND IT CHANGES OUR LIVES.

HE CHANGED MINE FOREVER.

AND "MAN'S SEARCH FOR MEANING" CAME OUT AFTER HE WAS IN THE CONCENTRATION CAMP FOR THREE YEARS.

AND "PURPOSE" WAS SEMINAL TO WHAT HE LEARNED.

I MEAN, HE HAD ALREADY WRITTEN ABOUT THIS, BUT WHEN HE WAS IN THE CAMP HIMSELF DOING -- SURVIVING, HE COULD GET UP IN THE MORNING AND GIVE SOMEBODY ELSE A CRUST OF BREAD, A KIND WORD, A SLURP OF SUPPORT, HOPE, AND EMBRACED HOPE.

AND SO GROWING AND GIVING IS ABOUT EMBRACING HOPE AS HUMAN BEINGS REGARDLESS OF THE SITUATIONS WE'RE IN.

>> Eric: WHAT'S MIND OVER MATTRESS?

[ Laughter ] >> YOU GET UP IN THE MORNING, ERIC, AND YOU DO THREE STEPS.

NUMBER ONE IS AUSE.

NO CELL PHONE.

SECONDLY, TAKE THREE DEEP BREATHS TO GROUND YOURSELF.

AND THIRD, HAVE THE INTENTION OF, WHAT AM I GOING TO TODAY TO MAKE A DIFFERENCE IN ONE OTHER PERSON'S LIFE.

THERE ARE 1440 PURPOSE MOMENTS IN A DAY.

YOU CAN FIND AT LEAST ONE OF THOSE MOMENTS TO REACH OUT AND GIVE SOMEBODY ELSE HOPE.

OR A KIND WORD.

OR SOMETHING LIKE THAT.

AND SO MIND OVER MATTRESS IS THAT.

>> Eric: THERE ARE SO MANY DIVISIONS IN THE COUNTRY RIGHT NOW.

AND THERE'S AN EPIDEMIC OF LONELINESS WE'RE TOLD.

AND PEOPLE AREN'T WORKING AT THEIR JOB ANYMORE.

THEY'RE HOME.

THE ATMOSPHERE CHANGE A LITTLE BIT FOR YOUR PRESCRIPTIONS?

>> NOT REALLY.

BUT ISOLATION IS FATAL.

WE KNOW THAT.

AND IT'S FATAL FOR OLDER PEOPLE.

IT'S FATAL FOR YOUNGER PEOPLE.

AND SO DON'T GO IT ALONE.

BUT IT DOESN'T MEAN JUST PUT ON A HAPPY FACE.

PEOPLE DO BETTER WHEN THEY GIVE TO THERS.

EVEN PEOPLE WHO ARE DEPRESSED OR FEELING CERTAIN PAINS IN THEIR LIFE.

WHEN THEY GIVE TO SOMEBODY ELSE, THEY DO BETTER AND THEY FEEL BETTER.

AND O I'VE BEEN INTERVIEWING PEOPLE ON YOUR OPENING QUESTION, ASKING THEM IF THEY COULD LIVE THEIR LIFE OVER AGAIN, AND THERE'S THREE THINGS THAT HAVE COME OUT THROUGHOUT THE 40 YEARS.

NUMBER ONE, THEY'D BE MORE REFLECTIVE THE SECOND TIME AROUND AND USUALLY THEY WOULD BE REFLECTIVE WHEN THERE WAS A CRISIS, PHYSICAL, EMOTIONAL, FINANCIAL.

SECONDLY, THEY'D TAKE MORE RISKS.

PARTICULARLY IN THE AREA OF RELATIONSHIPS AND WORK.

THOSE ARE THE TWO BIGGIES.

WORK AND RELATIONSHIPS.

BUT THE THIRD THING IS THEY WANT THEIR LIFE TO MATTER.

MATTERING MATTERS.

OF THE -- 'LL SAY THOUSANDS OF PEOPLE OR HUNDREDS OF PEOPLE I'VE HAD THE PRIVILEGE OF INTERVIEWING, EVERY SINGLE ONE WANTS THEIR LIFE TO MATTER.

THEY WANT TO LEAVE THEIR DENT, AND THEIR -- DO THEIR PART.

>> Cathy: YOU JUST TURNED 80.

CONGRATULATIONS.

[ Laughter ] HAS YOUR PERSPECTIVE CHANGED?

AS YOU HIT INTO THIS CHAPTER OF YOUR -- HE NEXT CHAPTER OF YOUR LIFE?

>> NOT A WHOLE LOT IN TERMS OF PURPOSE.

I STILL BELIEVE IN THE CORE MESSAGE OF "THE POWER OF PURPOSE."

AND WHAT IT CAN DO FOR -- AND HERE'S WHY.

PURPOSE IS FUNDAMENTAL TO HEALTH, TO HEALING, TO HAPPINESS, AND ULTIMATELY TO EVEN TO LONGEVITY.

AND SO I -- AND AS I LOOK AN AGING POPULATION, MORE AND MORE PEOPLE ARE WANTING TO DO PURPOSEFUL THINGS WITH THEIR LIFE ALL THE WAY TO THE END.

END IN MIND.

>> Cathy: YES, EXACTLY, HE END IN MIND PROJECT.

"THE POWER OF PURPOSE," FOURTH EDITION COMES OUT NEXT MONTH.

>> Eric: GREAT HOLIDAY GIFT.

>> Cathy: 40 YEARS BETWEEN
