When you keep trying to do something over and over again, and still aren't happy with the results, it might be time to let go and move on. This doesn't mean you've failed or you'll never be able to go back and try again; it simply means the timing was off and there's something better waiting for you.
When you let go of the old, you make room for the new. Trust your Guides and your inner knowledge to know when the timing is right. When things start falling into place at lightning speed, and your sense of frustration is replaced with hope and the excitement of embracing something new, you'll know you made the right choice.
