How it shows up
This is perhaps the purest form of the third line: these people learn only by living an experience all the way through. They rarely know in advance what will work, so they dive into new things boldly. The strength lies in an assertiveness that turns a mistake into an advantage: what failed becomes a pointer for the next step. Treating setbacks as information rather than a verdict, every finished cycle makes them more mature and confident.
At its best
The energy to accept mistakes as part of growth and turn them to advantage: getting up quickly and moving on, a little wiser each time. That resilience encourages others not to fear trying.
The shadow
Moodiness in which a mistake becomes a reason to brood and grow overly cautious. Cycles stay unfinished because fear of repeating the error freezes everything.
Exaltation and detriment
In the activation table the line is marked ▲ (exaltation) when it is activated by Mars, and ▼ (detriment) when by Moon. Exaltation brings out the line at its best, detriment its shadow.
