Hinduism has a long tradition of precedence of spiritual growth over the material accomplishments by exercising an equipoise mind, fruitless karma and righteous duties prescribed in scriptures. In this tradition, rather than considering it disadvantage or negative attribute, being alone was traditionally treated as a blessing sort, which provided an opportunity to introspect and realize Self. It is only in solitude that a person could meditate in quiet moments to discover Self and Supreme Truth of the universe. 

This is the reason why many accomplished Rishis in ancient India preferred to live in isolation in forests, and consequently discovered and gave true wisdom and knowledge to the mankind through infallible Vedas and Upanishads.
