Do you set your goals annually, monthly, weekly, or not at all? Goal-setting is an oft-discussed key of leadership and effective management, but can you have too much of a good thing? Last week, goal-setting was a hot topic on the blogosphere, and the following are some highlights:   Leadership Styles Blog discussed "backwards planning," one strategy for achieving goals. Nina Simosko discussed another strategy for achieving goals - "picking your preferences." Reminding us that not all goal-setting is perfect, Learn This discussed potential pitfalls of the exercise. Will at Work presents research regarding unintended consequences of goal-setting, as well as how goals can help measure workplace performance. It's fine Monday material to mull over as you start your week.
