Each of us has his or her own individual personal path. Our path in life is as unique as our fingerprint, in accordance with our mission in life, former reincarnations, and our individual tikkun. Although there are general tasks that each person must do on this earth, each person has a unique and individual way of completing a given task. One cannot attain happiness or fulfillment in life without ascertaining his or her unique path. Without personal prayer, this is virtually impossible. Personal prayer can't be found in any book; not only does it change from person to person, it changes within a person himself from day to day and from hour to hour, according to a person's current circumstances and according to the stimuli that Hashem sends at that given moment. - The Garden of Yearning
