Should you focus on the past and feel as if you’re doomed to repeat it, and that you’ve created immutable character defects, or have changed into a permanently diseased addict or alcoholic doomed to relapse? Should you beware of your disease, avoid overconfidence/arrogance and simply take things “one day at a time”? Maybe it’s better to believe that you can change permanently, and to envision a better future for yourself. Maybe it’s better to simply think about those things that would make you happier than a cheap high and to work towards those things. That’s what I think anyways, and I think Martin Seligman would agree.
