I personally have a passion for dance, music, fashion, writing, learning, acting, and teaching. I also saw limitless and knew there was a substance as being an acting you know movies scripts usaully come from a persons real life experience or someone they screen wrtiting knew as a result of the film concept & storyline. This would be a hiccup to an an individual who does have an addicting personality. So you most face your fears with creating a chemical balance between you and the substance based off YOUR DNA!
Experimenting from a safe distance is the BEST way to go IMO. Research, research, research!!!!! Internet is free and so is knowledge* DMT
