Redrum - Inside Jack's Torrance mind

Meet Jack Torrance, a middle age English teacher with a heavy temper and a recently sober lifestyle, married to Wendy -a sensitive woman who has given up on love and life- and father of Danny, a perceptive five-year-old with a sixth sense and a flowing imagination, but we will focus on Jack.
To settle a background, we know until this part (Chapters 1-6) that Jack has lost his temper many times, and it took away from him his cherished job as a professor, and some considerable part of his wife's love. He's got issues. With himself, with his life, with alcohol, and, with others. Now, due to all those "accidents" and hangovers, he had to take the job at The Overlook, a lonely hotel in Colorado with its own life and voice, that soon would become the horrifying stage of mental journeys, and Jack's constant battle to keep lucid and sober.
According to my perception, Jack Torrance represents the dark reality of that time in the author's life, Stephen King, who was in the deepest struggle with addictions towards alcohol and cocaine, wich are clearly shown in the novel, but of course, adding a little bit more of violence and a dimmed perception of reality.
Jack is truly interesting, and throughout the reading of the marvelous and shady piece that is "The Shining", we will get to know him -and all the different characters inside of his amazing brain- but we'll also learn more about ourselves, like how it would be able to us to manage distinct scenarios during several mind states in our lives.
