Even if you're not particularly superstitious, it's easy to ascribe the things that happen to you in your career to luck (either good or bad). In fact, you can make your own good luck at work, just by making a few simple changes in your life.
Unless you're a Major League Baseball player, you probably don't readily admit to being a superstitious person – at least not at the office, where being sensible and making decisions based on data is part of projecting a professional image. But in reality, most of us do harbor at least one or two totally baseless beliefs. Sometimes, these are harmless (astrology lovers, we're looking at you) but sometimes, superstitions can keep you from achieving your goals. If you recognize any of these, use this Friday the 13th to engage in a little cognitive restructuring.
When it comes to your career, there's a lot that's outside your control. You can't make a job opening appear when you really need one, or keep an awesome boss from transferring to another department, or boost the budget for raises and the opportunities for promotion. At the end of the day, pretty much all you can control is yourself and your behavior. The good news is that sometimes, that's enough.
