Long makes it hard to read and follow. The thinkers probably already know the points but are too entrenched; family, time, position. A few may still think they are a force for change jnside.,(Simon once felt that way from what he said)
By our age we mostly discover we are wrecks and have not had colorful lives whether jw's or not. A lot of us do have successful marriages, and homes. The pioneers, COs etc. do have things to regret.
We born ins are more likely to regret careers not taken because of education lack. Forest ranger, doctor, etc. Then there is the overtime crap.
