Adrien paused for a second, gathering the courage to express himself. "Thank you -- thank you so much. I haven't even started, and you've already been such -- such an invaluable help".

"Ah -- don't mention it, really", the sorcerer Valerion smiled, slightly shaking his head. "I am glad to hear that, though".

Adrien smiled back at him, nodded, then turned around again. With resolve, he placed his chalk on the surface of the wall, then quickly moved his hand to draw a circle, which came out rather ugly.

"Aw!", Adrien chuckled. "Here we go again!". He wiped the circle off the wall, then replaced it with a second one - not any prettier than the first. He wiped away this circle too, and he drew a third - perhaps slightly better than the previous two, but still not close to being satisfactory. Adrien smiled; he wasn't discouraged at all. He kept well in mind what the sorcerer Valerion had told him before - maybe he will have to draw one hundred failed circles, maybe one thousand, but, eventually, he will succeed; each failure will bring him closer to his success. If that was the case, he told to himself, then each new failure was not only to be accepted, but even welcomed.
