Just as corporations benefit from having a well-defined mission statement, your personal mission statement helps you navigate your career through turbulent times in the workplace. Similar to a mission statement for an organization, a personal mission statement is a declaration of who you are and what you want to accomplish. However, it offers a powerful voice to what's important, meaningful, and fun for you. New career goals will be easier to communicate. It's imperative that at some point you write down this mission statement.
Some people dive right in and draft versions until it becomes clear.
Others prefer spending time talking out loud or to a trusted friend, and then writing it down. Whichever style works for you, get it down on paper. Don't let grammar, spelling, sentence structure, or style stop you. It's unlikely you will clarify and narrow your mission until several drafts have been made so do not be discouraged if your mission doesn't seem to fit the first time. Your mission statement will be unique but it can be helpful to look at a couple short examples.
