Restlessness comes due to some desire or the other of which we are not yet conscious. The desire pushes from behind, the nerves respond trying to reach out to the object of desire. But since the mind has put a cover of unconsciousness the nerves do not know what to do and where to go. Hence the restlessness. One should grow conscious of what one is looking for in life and make conscious choices about life goals etc.
As to books, my favourites were Jonathan, Livingstone, Illusions, Prophet (Khalil Gibran), Gitanjali, Kalidasa, Anandmath, stories by Sharat Chandra, Acharya Chatursena, Rangeya Raghav, Rashmirathi by Dinkar, Plato, Homer and many others. One should read and read widely. It is a habit we have largely lost, but one that is very helpful in many ways.
Affectionately,
Alok Da
