Who you are

You are the person people ring when they have read the letter three times and still do not understand it. You do not simply repeat it slower. You find the one comparison that makes the whole thing click, usually something from ordinary life, and you watch their face to see whether it landed before you go on.

You are also honest about what you left out. When the simple version stops being true you say so, and you are willing to throw away an explanation you have used for years because a better one turned up. Most people defend their old explanations. You treat yours as temporary, which is why they keep improving.

Your gifts

• Clarity. You can explain a hard thing without making the listener feel stupid for asking.
• Honest shortcuts. You say which parts you simplified, so nobody walks away overconfident.
• Willing to rebuild. You drop a favourite explanation the moment a truer one appears.

Your shadow

Left alone, understanding becomes a substitute for doing. You can explain your own situation beautifully, the whole pattern, where it started, why you repeat it, and then change nothing, because the explanation feels like progress. You also reach for the model when someone is upset, offering a framework where a person wanted to be sat with. Knowing why is not living differently.

Your soul work

Your work is to act on one thing you already understand perfectly. Pick the pattern you have described to friends a dozen times and change a single behaviour inside it this month. You have done the thinking. The rest of it only happens in the part of your life you can be seen living.

Days you get along with

Your sign

The ninth sign fires its arrow at the horizon and follows it. Sagittarius carries the gift of faith in the distance, and the lesson of being here.

Someone else

Look up another birthday

Check a friend's day, or your partner's, and send it to them.
