How often do you bother thinking about the reputation you've built? Reputation can make or break a career. You many enjoy reading the following things on reputation I had learnt from Seth Godin:
1. Your reputation has as much as impact as you what you actually do
2. Early assumptions about you is really sticky
3. You cannot "game" your reputation. Even if you did, it doesn't last.
4. The best way to maintain reputation is to keep doing things that you are proud of.
5. Good work is of maximum value only if the people get your reputation right
6. Many people do not bother building a reputation at all!
7. Be prepared to live with your reputation for long, because you need to
8. Most important: Because not everyone can talk to you, your reputation is built by others.
Be your reputation, early and often, and you're more likely to have a reputation you're glad to own.
