There are all kinds of ways to gain feedback, and Gen-Yers have become more successful than their elders at the process. Rypple, (where I have a guest blog) has designed internet solutions for gaining feedback. Kudos to them and to you for making bottom up feedback solutions available.
My question. What are you going to do with the feedback once you get it?
Sure. Feedback is necessary for you to improve your work performance. Although it sounds cliche, it's also true that when professionals seek out help, they are not usually as well-prepared as they should be. To make the most of future feedback opportunities, you need to understand yourself well. And that includes your strengths, weaknesses and relationship skills. Only with that knowledge will you be able to figure out who to turn to for further developmental support. In other words, the smarts for targeting mentors requires an ever-growing self-knowledge.
"Know thyself," is not mere banter from Plato, the world's most influential philosopher. It's the profound key to a rich professional life. Marcus Aurelius, the Roman emperor who was revered for his literary output, elaborated still more: Look well into thyself, there is a source of strength which will always spring up if thou wilt always look there.
