BjjBrick Q&A 19 Am I Too Passive?

Question: I’m 3 months in and I have a question for you. I’m 38 years old and most of the guys at the school are in their 20’s. they have high energy, they’re fit, they move quickly. I just don’t seem to have an intense killer instinct to win a roll, I’m a very passive personality, very submissive, I was never into sports. I recognize Jiu Jitsu as an effective FOR of self defense that I may need one day and I’m sure if needed I could operate at 110% in an emergency, but in a roll I just don’t seem to have an intensity that I see others have. Do you think that’s something I could develop over time or something that can be taught?
