Omar Khayyam had the Right Idea

Come, fill the Cup, and in the Fire of Spring
The Winter Garment of Repentance fling:
The Bird of Time has but a little way
To fly---and Lo! the Bird is on the Wing.

We are here for a short time. What is the use of wallowing in repentance? Especially in repentance of imaginary 'sins' that have harmed no-one.

Time spent being miserable, or making others miserable, is time wasted. Instead of worrying about future things we cannot know anything about, we should enjoy ourselves, and each other, now.

Here with a Loaf of Bread beneath the Bough,
A Flask of Wine, a Book of Verse---and Thou
Beside me singing in the Wilderness---
And Wilderness is Paradise enow.
. . .
Ah, make the most of what we yet may spend,
Before we too into the Dust descend;
Dust into Dust, and under Dust, to lie,
Sans Wine, sans Song, sans Singer, and---sans End!

And to the many that have told me - "you'll regret your unbelief when it's too late", I say, - you will regret your lost opportunities when it's too late. Enjoy life, with old Omar Khayyam.
