Meaning

Meaninglessness is a condition in which the soul has a loss of purpose. A meaningful existence has three ingredients:
1. Purpose
2. Prudence
3. Pursuit

One can also look these as
1. Worth - What one considers worth living for
2. Wisdom - What one knows about how to pursue what's worth for
3. Work - What one does in order to gain what's worth gaining

Also,
1. Love - Love is the strongest compeller.
2. Leading - Direction
3. Labor - Action

Again,
1. Motivation
2. Means and Methods
3. Ministry
