"Solitude was seminal in challenging the established belief that "interpersonal relationships of an intimate kind are the chief, if not the only, source of human happiness." Indeed, most self-help literature still places relationships at the center of human existence. Lucid and lyrical, Storr's book cites numerous examples of brilliant scholars and artists -- from Beethoven and Kant to Anne Sexton and Beatrix Potter -- to demonstrate that solitude ranks alongside relationships in its impact on an individual's well-being and productivity, as well as on society's progress and health. But solitary activity is essential not only for geniuses, says Storr; the average person, too, is enriched by spending time alone."--Back cover.

Many people have historically chosen solitude for religious or spiritual reasons, to focus on something they wanted to achieve, because they just preferred being alone, or for many other reasons.
Many societies have stigmatized solitude and those who choose it, but on the other hand there have been social movements which have praised and advocated solitude.

There are some good books on the subject. Solitude: A Return to the Self by Anthony Storr was one of the first I read and had a strong focus on psychology. For a more opinionated text, Party of One: The Loners' Manifesto by Anneli Rufus was good at building confidence in living this way.
