What breakthrough? Lets just start with the fact that I'm a low energy person, sensitive to any life stressors, and prone to depressions, who is not fully satisfied with life despite being a successful professional on paper (glass half empty). I fooled with supplements/DIY treatments on and off for 2-3 years, but only in the last year it became a full fledged, full time hobby. Don't get me wrong, i did fine tune my stack and it helps some, but it's a slow, evolutionary process.
this is the first time i feel a massive improvement, although it may sound trivial for a normal, young, and well functioning person (well, i'm neither of those): 2 days in a row i'm waking well rested about 4AM and decide it's a good idea to get up and walk around my hilly neighborhood for an hour, later not going back to sleep, but doing some other things before work. This is all without any traditional stimulants (i nearly eliminated caffeine weeks ago as part of my stack fine tuning). I also find myself more relaxed, less irritable, more productive at work, and i eat healthier. I suddenly feel younger a couple of decades. I only hope this will last.
what did i do differently? a few different things happened recently, but the best i can time the events it must have been dusting an old book that i enjoyed as an adolescent and reading it again. I don't think the choice of book is important, except for the fact that this is my native language, it's something i felt strongly as a young man, and has incredibly rich language while dealing with heavy duty philosophical shit, while disguised as a sci-fi fiction.
reading the pages and especially words that i forgot they existed is almost like rediscovering a lost treasure and peeling layers of memory that are coming back to life. it's not an easy read though, i can only do 20-30 pages max in PM before getting tired going to bad early.
so, my dear fellow longecitians, see if there is something you deeply enjoyed on an intellectual level earlier in life, especially something that changed/built your personality, that you can do again and see if that rejuvenates yourself. please report back.
