In the past I have written about analyzing your current job, your job prospects and your career as a whole. You should always have some idea where you are headed in both life and work. That said, It is possible to focus on your ideal career so much that you are never quite happy with what you have. Career planning can be more of an oxymoron than you might first believe.
People often end up in places far different from their original plans, both better and worse.
While you can direct your career, controlling it proves to be another story. I know that career planning is a lost art akin to divination and alchemy. I have always had a direction in my career but life has a way of sending you down curving roads where you can't see what's around the bend. If you would have asked me years ago whether I would ever work for The Walt Disney Company, a mutual fund company and a web site company providing movie information I would have said no. Life is odd.
