He excelled in his responsibilities from an early age
According to the Ashokavandana (Ashoka's story), Bindusara, the second Mauryan Emperor, despised his unattractive son Ashoka. Bindusara sent Ashoka to the important city of Takshashila (now Pakistan) when he was in his twenties to put down a rebellion in the region. Bindusara may have intended Ashoka to fail in this endeavor because the city was about 1500 kilometers from the Mauriyan capital of Patliputra (modern-day Patna, India). The young prince, on the other hand, was fast to follow his father's directions, took command of the situation, and excelled in his responsibilities.
The uprising, however, is not mentioned in preserved Sri Lankan writings such as the Mahavamsa. Bindusara named Asoka as Viceroy of the Ujjain Province, which was a major administrative and commercial center in Central India at the time. Ashoka performed admirably in this job and showed that he was a capable administrator. In light of one or both of these sources, it's worth noting that, despite his father's disapproval, Ashoka was given key tasks in his early years.
It can be seen that the fulfillment of responsibilities from an early age by the great Ashoka proves that he is a multi-talented, intelligent, and discerning person. Not only that, it was the responsibility of a top leader, to show Ashoka's ability.
