Obsession can be good and bad. Part of what has driven many sucessful people over the ages is an obsession to succeed, to be the best, to do more, be more. Sadly most often times obsession manifests itself in a darker form. The obsessor rarely knows that they are obsessing. The turning point for me was to realize when I was obsessing and actively curb the habit. Sometimes its as simple as just letting go. Other times it requires a great amount of determination. I still find myself obsessing over tiny details, repeating things over and over for no good reason. But like all “habits” the behavior can be unlearnt. Just takes time; patience.
