Let’s take as example a 80+ life span. The first 20 years is the spring when we put the seeds in the ground. It’s like a friendly sanguine. This is learning time!
The 20-40 years span is the summer where we work the ground and we need water to grow. It is like the diligent choleric. This is living!
The 40-60 years span is the autumn where we reap the fruits and we love life, It is like the fruitful melancholic. This is loving!
The 60-80+ years life span is the winter where we enjoy the fruits and we leave a legacy. It is like the thoughtful phlegmatic. This is a legacy!
