This is a vital point to consider. Thank you for sharing your experience
You can usually gauge when a person begun based on the sport or style they have chosen to pursue. The OP began with BJJ because of seeing the Gracie performance in UFC1 and wanted to emulate - we often pick a martial hero to aspire toward, it seems to be a common human trait.
As a youngster fighting was a daily experience. We lived in a rough part of town
A Karate dojo opened up nearby and it was supposed to be a tough place to train. It was a kyokushin dojo and we were active kids seeking a challenge, so we joined. The physical training was tough, everyone was given the same treatment regardless of their age. At the time I was not even 9yrs old, but I loved the tough training regime and made some good friends.
We learnt the katas and the techniques, took the gradings and began testing the techniques. It soon dawned on me that most of this stuff was not applicable to reality. The lessons and directions being given were perfect for sports events and demonstrations. The reality of using them in real fight situations was about as close to useless as you could possibly get - this kind of teaching would be funny if it was not so dangerous to those who believe it.
It was not all bad though. As a result of joining the club I started reading around the subject and came across the spiritual aspects and philosophies of the martial way, and it is the spiritual aspects which have given me the greatest benefits over the years.
Along the way, I took Western Boxing and Aikido as my main arts. These two gave me a good grounding from which to investigate other styles. These days I am quite partial to the CMA, especially Taijiquan and the other internal practices. It requires more discipline to heal, and it is 100% more important than winning trophies, gaining belts or learning how to harm.
"The Way of a Warrior is based on humanity, love, and sincerity; the heart of martial valor is true bravery, wisdom, love, and friendship. Emphasis on the physical aspects of warriorship is futile, for the power of the body is always limited." ~ Morihei Ueshiba
