A significant part of “knowing thyself”

is knowing what you will regret.

For teens devoid of experience, predicting future feelings is rather challenging; highs are higher and lows are lower as a result.

With, however, wisdom and the accompanying confidence to say “I know who I am,” if you pause before making a decision, an accurate sense of what action will produce regret appears.

And just like that you have earned a remarkably robust, intelligent philosophy for a good life: anticipate regret and avoid it.
