We know that seeds sown....

....in fertile ground will take root and grow. Similarly we can expect ideas and experiences to expand and increase in our imaginations over time. And in the same way that plants often look strikingly different once they have become established, so our memories and impressions stop resembling the realities that first gave rise to them.

That's why we should always be wary of overly romantic notions, and it is also why we should mistrust many of our deep-seated regrets and resentments.

When we are unable to find tranquility within ourselves, it is useless to seek it elsewhere. 
(Francois de La Rochefoucauld)
