He ran for office and was elected chief magistrate of Carthage where he enacted reforms that restored his office to its former prestige and refinanced the tribute to Rome so it could be payed in installments without extra taxes. He also reformed the hundred and four(Carthage’s senate) so that its members were elected by the people and changed the office from a lifetime appointment to a year with a max term limit of 2 years. After 4 years he went into exile to appease the romans who feared a Carthaginian resurgence. So he clearly was doing a decent job if it was scaring the Romans.
