As a lawyer, you must have contacts, but what you said is only one aspect (and you don't rely on them, you rely on yourself).

Even if the relationship is particularly good, you can't do it without professional knowledge. By successful lawyer, do you mean somewhere? Or the whole country or bigger? In a certain place, your judicial department has a good relationship, and you may do well, but what about the whole country or beyond? Can we have a good relationship? Then you may become foreign minister. So it's true that you have the ability.
