Want to learn trading, get into development, or research on-chain data analysis? Actually, advancing in any of these skills involves four key stages.

**Level 1: From Stranger to Understanding**
This is the most basic accumulation stage. You need to spend time reading materials, attending courses, and practicing hands-on. Whether it's learning candlestick charting techniques or smart contract auditing, this step cannot be skipped.

**Level 2: From Understanding to Unfamiliar**
Knowing ≠ Being able to do. Many people get stuck here, thinking they just need a bit more preparation. But that's not true—you must grit your teeth and start trying, even if it's rough. Through repeated failures, losses, or bugs, you'll truly grasp the patterns.

**Level 3: From Unfamiliar to Skilled**
This is the polishing stage. Focused, deliberate practice repeatedly, gradually finding the most efficient workflow. Avoid detours—simplify complex concepts into core points.

**Level 4: From Skilled to Mastery**
Real experts are those who repeatedly practice intensively in a short period, internalizing patterns into instinct. Your subconscious can help you make the right decisions—that's true mastery.

These four stages are indispensable and there are no shortcuts.
