Well, once you reach certain age you may notice things, people, their issues and everything else keeps repeating with just small variations. Its like playing a game - you have certain paths and choices, but at the end (almost) everything and everybody falls into certain category already shared with similar cases, with similar behavior, side effects and outcomes. Then very few matters will surprise you, and you may notice there are actually just few paths to true, long term life paths to life satisfaction and happiness.

You may reach that age and knowledge too, or not, what do I know.
