In Episode II Philosophies Of Life:  Life Is Not A Dress Rehearsal: Nathaniel Schooler and Steven J Manning discuss:

Life Is Not A Dress Rehearsal

Life Without Passion Is Not A Life Worth Living

Seek Knowledge Every Day 

Inventory Of Knowledge Every Day 

Life Is Exhaustively Scripted Tragi-Comedy

Here are some of Steven's thoughts and talking points: 

"* For you personally, if you have all your basic needs met, do you feel you have enough in life?

First, allow me to give you my rather pedestrian definition of success: to have options in life. 

Being able to seek and find satisfaction in life in ways that I want to and am able to pursue, not at the expense of others. This from my column Pillars Of Success, which is the most often requested talk and interview I am asked to give. 

No. I do not have enough in life. 

I hope and pray I never will. 

As written herein-above, I live with certain philosophies, those that guide my life. Top of the list are two:

∙ LIFE IS NOT A DRESS REHEARSAL

∙ A LIFE WITHOUT PASSION IS A LIFE NOT WORTH LIVING

Is all that a source of discontent for me? I admit to some dark hours and days, therefrom. However, mostly I think it is rather challenging. 

I think there is much to say about being the unhappiest person in the room, at the conclusion of a fabulously successful project, because of the certain knowledge that I could have done better."
