Completely new to trading—where should I start learning?

Hi everyone! I recently started a new job and I’m planning to set aside some of my income to learn and eventually get into trading. The thing is, I’m starting completely from scratch—I don’t have any background or prior knowledge about how trading works, whether it’s stocks, crypto, or other markets.

I’m really looking for solid, in-depth guides, beginner-friendly tutorials, or even structured learning paths that can help me build a strong foundation. I’d prefer resources that explain not just the “how,” but also the “why,” including risk management, strategies, and common mistakes to avoid.

If you’ve been in a similar position before or have resources (courses, books, YouTube channels, or even personal advice) that helped you when you were starting out, I’d really appreciate your recommendations. Thanks in advance!
