2. Your first "yes" moment."

According to millennial career expertJill Jacinto, there comes a moment for every employee in which -- suddenly -- your boss isn't available to do his or her duty, and he or she asks you to step up to the proverbial plate, like, to give a presentation you weren't prepared to give. (Talk about intimidating.) "Your immediate inclination may be no, no,no," says Jacinto, "but to move forward in your career, you need to say 'yes.'" By saying "yes" to the things that scare you, Jacinto says, "you are letting yourself be challenged." And that's when big career changes can happen.

"We all make mistakes," commiserates Morgan. And your firstwork screw upmay seem like it will break your career. But, "before you try resolving the problem -- or worse, sweep it under the carpet -- run your solution by a trusted employee," she suggests. "Depending on the size of the problem, you may need to check with your manager. It's important toadmit you were at faultand what you plan on doing to rectify the issue. By bringing your mistake to the attention of the appropriate leadership, you show that you are aware of your mistake and taking responsibility."

You know it's coming. So, "whether you've been asked to complete a summary of your year's performance or proactively arrange a meeting with your manager to discuss your accomplishments over the past year, it's up to you to make sure you take credit for your work," says Morgan. (Failing to do so could break your career.) "Keep arunning list of the big and small achievementsyou've had," she suggests, "and update it at least once a month. Not only will this help you track your success, it can be useful for regular meetings with your manager as well as the annual review."

Here's why: "It demonstrates to your potential new boss -- that you are willing to ask the hard questions and fight for what you want," says Jacinto. "If you don't negotiate these items, you'll keep playing a game of catch up to your industry peers."

Chances are, you won't stay in the same position or with the same company forever. One day, you'llquit for the first time. "When the time comes and you need to quit your job,always do it with professionalism," advises Morgan. Part of that "means keep your news top secret until you tell your manager," she says. Another part is giving an adequate amount of notice when you do quit, which could be two weeks or more. "Never complain or give the negative reasons you are leaving," she says. "You don't want to burn bridges that could hurt your reputation. Instead, say thank you for the opportunity and leave it at that. Be sure to ask your manager how and when your resignation will be announced or if you can notify your colleagues and clients."
