In 2012 I realized there was something wrong with my brain, the way I was acting and living wasn't normal. 6 months later I sat down with my wife and we tried to make an appointment with a psychiatrist. It never happened because I was arrested due to my abnormal behaviour and spent the subsequent 8 years in jail. That was as bad as realizing that the 20 years before that had been lived vastly suboptimally.
You only have one life to live. It sucks if you're not living it at 100% of your capacity.
