A time of reproduction and child-bearing.
But we are not all willing or able or called to bear children.
Some of us generate ideas and vision.
Some of us sow seeds for future generations to reap.
Some of us nurture and enable and empower the children of others.
Consider these words by Thich Nhat Hanh...
"When you plant lettuce,
if it does not grow,
do not blame the lettuce."
