I'm not sure what you mean by 'comfortable'.
But let's assume you mean 'figured out life'. I used to think that people knew what they were doing as they were getting older.
I'm still 'young', my wife and I are late 20s, early 30s. And I have given up the idea on 'figuring it out'.
Just on of the points would be how different the world looked like 60 years ago.
