Leslie John, associate professor at Harvard Business School, has done some deep research into the ways that people self-promote in their professional lives and identified what works and what doesn't. She says it is possible tout your own accomplishments without annoying your colleagues, if you do it at the right time or enlist others to boast on your behalf. She notes that many common workarounds -- such as humblebragging -- are highly ineffective and advises people to not only look for more natural opportunities to self-promote but also try to present balanced views of themselves. She's full of tips you can put to work, even in virtual settings. John is the author of the HBR article "Savvy Self-Promotion."
