I definitely had advantages in that I knew tools like Khan Academy existed, was not battling depression, and also had talked to people who I admired and saw they were not so different than me. I also had a mother who loved me and a step-father who came into my life a bit later who cared, but they were dealing with some pretty big challenges of their own, including mental health, bad relationships, debt, children who were in and out of jail, and everything that comes with that. I do not like to spend too much time focused on race, but I am a white male, which was also an advantage.
At the time I was leveraging Khan Academy I was around 24, had distanced myself from the people I had grown up with who were not on a positive track. I also don't know how, but somehow I got it in my head that finance was the universal language and that learning more about finance was the key to understanding more about the world. So I was very focused on that. I had no clue what economics was at the time, but once I learned about that, I was addicted. Finding topics like that deeply interesting is a HUGE advantage.
At that time, I was living on my own and had a stable job managing a department at Home Depot. I slept on an air mattress and didn't have any money to speak of, but I had enough time on my hands that I could spend time at a coffee shop after work and on my days off working my way through the knowledge map on KA, starting with long division (which was humiliating) and learning how to do everything by hand, and then progressing from topic to topic. My goal was to not have to take a remedial math class at the local junior college (2 year colleges in the US). I spent months mastering basic math and worked my way to more advanced topics (1 million energy points on KA, not sure if that's a lot but I'm still proud of it).
One last advantage I had was that I genuinely enjoyed learning and talking to people, and it showed. And I was young. So people were willing to take the risk. Many people were willing to give me a chance, encouragement, and their time as I was making my way through school. If I had a question or was interested in a career or topic, I would just ask someone if I could call them or shadow them, and most the time they would say yes. I had nothing to lose by asking, and was always amazed how often it worked.
I try to share this with others who were in my position so they know it is possible.
Thank you for asking.
