Have you ever met someone who has "been there, done that"? Or bristles at new ideas because they had success another way before? Now, if this person is still achieving and growing, great! Talk with them and see what can be learned and translated for your situation. If they're not growing, business is down, etc., run away!
Here's a tough question to ask yourself, "Have you stopped listening, stopped trying and stopped growing?"
When you get to the point of not listening, you have choices.
You can continue doing the same old thing, and get decreasing results.
You can stick your head in the sand, and get your butt run over.
Or, in the infinite wisdom of Cher's character in Moonstruck, you can "Snap out of it!". Try something out-of-the-box (maybe it's just out-of-the-box for you - it's ok to copy what others are successfully doing). Will you always hit it out of the park? Of course not! But at least you'll stop (or at least slow) your downward spiral.
Take a moment to consider what you can do to improve your leadership in your business, in your family, in your finances or in your community. Seek out authorities in those areas who are experiencing continued success. Are you listening?
