Stick 98 sits with the image of someone digging the earth for gold, surrounded by a small jade field they keep dismissing as too modest. The verse doesn't tell you to stop studying or abandon the exam. It reflects back the quality of your effort — the part of you that suspects the late nights, the third practice paper of the day, the highlighter passes through the same chapter, are producing diminishing returns. The miner who goes mad chasing the last nugget is a figure worth sitting with here. You may already have what you need; you just don't trust that what you've already absorbed counts.
For a studies or exam question, this is a middle-grade stick, which means the outcome isn't fixed against you, but your relationship with effort needs adjusting. The verse points less to how much more you should grind, and more to whether you're studying the material or studying your own anxiety about the material. Notice which subjects you keep re-reading because you genuinely don't understand them, versus which ones you keep re-reading because closing the book feels unsafe. The jade field is small but real. The exhaustion of pretending it's a goldmine is what the stick is asking you to put down.
