The Stoic philosophers, Buddha, and Thoreau contemplated this question -
how to achieve tranquility.
Of course, Thoreau famously went to live in isolation in the woods for two years in search of enlightenment.

"I went to the woods because I wished to live deliberately, to front only the essential facts of life, and see if I could not learn what it had to teach, and not, when I came to die, discover that I had not lived."
