Don’t assume everyone knows about you or your accomplishments. Getting ahead often requires making those things more apparent. However, I say “toot” your horn, not “blow” it for a reason. No one likes a braggart. Be strategic about your self-promotion. For example, someone mentions they are working on a new project that requires XYZ skill; it’s the perfect time to mention your experience with that and offer to help. After all, the best way for people to learn about you and what you’re good at is to show them.
