Learning and Unlearning
One of my main takeaways from the book, Lessons of History, is that the vices of one societal revolution were the virtues in the previous one. For example, conformity was a virtue in the industrial age but a vice in the information age.
The same principle applies for different life stages. Ambition is a highly regarded trait in the young but isn’t for senior folks. Arguably, you should’ve already accomplished most of what you wanted to do.
Life is a constant state of what got you here won’t get you there. And a constant cycle of learning and unlearning.
