Stoic philosophy
Personally speaking, having faced much adversity in my life above and beyond that incurred in my drinking history, an example of which being that I twice lost everything, and In do mean EVERYTHING! Other than my son and my ability, which has also played a substantial part in my recovery... due to the selfish and irresponsible actions and behaviour of others in my personal and professional life, by developing a keen interest in the principles and practices of Stoic philosophy...
A good starting point of which is the website Stoicism Today, there are now books of the same name containing selected writings.... together with Jules Evans book, 'Philosophy for Life and Other Dangerous Situations' helped me in dealing with my past and present life immensely ... perhaps not least because they both contain links to the Serenity Prayer...
