Life Formula

Doing things the usual way
Brings known, repetitive, successful results.
This holds true for most things.
Consistency is the name;
Tried and tested is the ad campaign.
Measurable, quantifiable.
Add the element of chance and the game changes.
Sure, it is good to stick with a winning formula.
This only works in a lab.
Try the lab of life; experiment on repetitive, successful outcomes.
Oh, don't forget to add the elements of risk and chance.
See how your life formula turns out.
Risk and chance: Erratic, and never defined,
Of no fixed value, yet must be ever present in your equation.
Get a tried, tested and true formula for life,
And get back to me.
