Do you know who you need to know, and who needs to know you?
As you plan to approach the people who can make decisions and help you advance, create the right mindset. View yourself as someone who has the diversity of  skills and talents to make your organization successful. In fact, you would be doing your company a disservice by not sharing your abilities and being able to contribute at the highest possible level!
List the ways in which you’ve contributed to your organization’s success. Keep your list with you, and review it frequently. Whenever you feel a twinge of self-doubt, your list will remind you of your value.
While you work on building your inner confidence, develop relationships with colleagues you can enlist as champions. These people will sing your praises to others, and you, in turn, can sing theirs. Your champions can be people who work above you or peers on your same level—the point is to pinpoint those who have some kind of influence. Choose diverse allies whose opinions are respected so that when your name comes up, people will listen.
Between your strong professional relationships and your strong sense of self, you’ll be well on your way to being seen as a person of interest.
