We usually think of a bad attitude as a whiney and vocal one, and that's certainly true. But I'm talking more about the "poor me" talk that underlies all that, the talk inside your head that you play over and over and that other people don't necessarily hear. Believe it or not, you can be an incredibly positive person on the outside and still complain a lot on the inside.
There are many guises our poor-me voices can take. One that I find the most dangerous - and which is one of the more subtle ones - is the one that acknowledges that you're a martyr for a cause, that you're suffering for a purpose. This is a voice that both the positive and the more negative people of the world succumb to, often without being aware of it.
Martyrdom is generally seen as a good thing, and the commitment that underlies dying for a cause is certainly something to be admired. But the inner voice of martyrdom is not the same as that commitment. What that voice does - along with all the other voices that berate your situation - is set you up for powerlessness. Whether you're a martyr or not, you're seeing the situation as something outside of you over which you have no control.
You always have control!!! Your control is over your reaction, over your attitude. Like attracts like. When your attitude is one of openness and willingness to see a bigger picture, something beautiful happens. Sometimes the outer picture changes magically, and that's great. But more often than not, what happens is more subtle: Your attitude shifts your perception, and suddenly you don't see the situation as you did before. When that happens, the situation is no longer what it was, whether to other eyes it is or not.
Your perception is what creates your reality, and your attitude shapes your perception. What is your perception of your life as it stands today? Are you the martyr fighting for the cause? Or are you at the center of your life, calling the shots, going with the flow, enjoying the ride? Every moment offers you the choice to be either. What do you choose today?
