I have a problem that is holding my career back – I’m terrible with clients. I work in IT and have rapidly risen up the ranks over the last five years and am now second in command of a team. But I can’t see myself filling my manager’s shoes because I don’t deal with clients well. At meetings I feel like I say the wrong things and back at the office I find it difficult to hide my frustration in the face of clients’ constantly changing demands. In the future, I really want to be a manager who’s good at this side of the business. What can I do to improve?
