His approach

His advice is practical, tailored and to the point. "When I write an advice, I think carefully about how I myself would like to be advised: clear language, a concrete answer to the question and a solution. As a result, my advice is useful and actually provides a solution to the problem."

In addition, Jim is a go-getter who goes for the best result. And that is reflected in everything he does. "If I have a goal in mind, then I go for it full force. That might be, for example, an opinion or coming up with a solution and, if I have to, litigation. I don't give up easily."
