Tan Lang is the desire and peach-blossom star of the fourteen, and 慾 here isn't a moral judgement, it's life force: wanting a great many things, and meaning all of them. It's also classified as the star of talent, and those two come from one source — only someone interested in many things learns many things.
It shows up in you like this: your list of wants is long and every item on it is sincere; you learn fast, because interest is the best teacher; and you can't invest in what leaves you cold, going dull all over when you force it.
Running well, Tan Lang is energy itself: a vitality people want to be near, and you actually produce things. Blocked, unranked desire becomes drain — five at once, each touched only on the surface; or stimulation filling a hollow, at a rising dose. The tradition's treatment of Tan Lang isn't abstinence, it's 有制, being governed. Practically: rank them rather than renounce them. You don't lack drive. You lack a decision about which one this year.
