Don't be afraid to ask your boss for help on troublesome career issues.That's according to Beth Comstock, former vice chair of General Electric.Earlier in her career, Comstock was told by GE's CEO that she needed to be more confidentso she asked him to nudge her whenever he noticed her withdrawing.About six months into Beth Comstock's role as chief marketing officer at General Electric, then-CEO Jeff Immelt invited her into his conference room.As Comstock writes in her book, "Imagine It Forward," written with Tahl Raz, she assumed the conversation would be about a pending project.Instead, Immelt told her, "I need you to be more confident." He added, "I know how good you are, but I don't hear enough from you."Comstock, who was vice chair of GE until 2017, was surprisednot because she felt that she was confident, but because, she told Business Insider, "I thought I was a better actress than that."The truth was that not only had Comstock struggled with self-confidence her whole life, but she also felt ill-prepared for this new marketing role. At GE and at NBC, she'd worked in corporate communications.Read more:A former GE and NBC exec was nearly passed over for a big promotion because she made an all-too-relatable mistakeOnce Immelt's feedback had sunk in, Comstock took a series of steps to display (and feel) greater confidence. One such step, she told Business Insider, was asking Immelt to help.Going forward, whenever he saw Comstock withdrawing or hesitating to speak, he would say, "Beth what do you think'" or, "Beth, I've heard you express an idea about this in the past. Could you share that with us'"That way, Comstock said, she felt accountable to Immelt. Plus, he knew she was working on the issue.In "Imagine It Forward," Comstock writes that she also made a point of coming to Immelt's meetings with strongly articulated arguments. And instead of prefacing comments with phrases like "This may be stupid, but" she simply said what she thought.Comstock also learned that, as a manager, it's important to help your employees developComstock spoke about that period in her career with Business Insider's Richard Feloni, on an episode of the podcast "This Is Success." She said she eventually gained enough confidence to admit what she didn't know and ask for help. "People were very generous, and some people didn't have time for me and you find the ones who do," Comstock told Feloni.Not only did the experience teach Comstock about the importance of accountability, but it also taught her an important management lesson.Comstock told The Washington Post's Jena McGregor that Immelt could have "written it off and said, 'I'm not going to assign her to the next thing, because if she's not confident enough, how can she do this'' Instead, he spoke to her about the problem."I think leaders need to do that," Comstock told McGregor. "You help the people who work with you be better. I try to emulate that with teams I work on."SEE ALSO:'It's not like I had this well-oiled plan': Former GE and NBC exec Beth Comstock reached the C-Suite by taking things one day at a timeJoin the conversation about this storyNOW WATCH: Why most people refuse to sell their lottery tickets for twice what they paid Click here to read full news..
