There are very often things you can do to change a situation. It does require big girl panties, sure. But I think it's empowering to know we aren't out of options except whining. No, we can choose to take action. We are powerful. The trick here is to let go of what you can't control. And certainly to stop whining about it. Instead, focus that energy on what you actually can do and let the rest go.
Man, I've been down the road of kind of trying but not really in EVERY aspect of my life. And wondering why my house wasn't clean. Why my kids were acting crazy. Why my finances were going nowhere. Why I was overweight and out of shape.
