What’s the Best Foundation for Your Trading Strategy?

I’ve been diving into trading more seriously lately, and I keep hearing about how important it is to have a solid foundation. But honestly, I'm a bit confused about what that really means in practice. Some say it's all about risk management, while others emphasize technical analysis or market research.

I’d love to hear what you all think. What’s your personal foundation when it comes to trading? Do you lean more towards a particular strategy, or do you mix several elements? Any specific resources or experiences you think could help someone build a strong foundation? Just trying to soak up as much info as I can!
