We live in an unlimited Universe and are constantly discovering new information about it. There are no shortages in the Universe, the only shortage is our mental ability to comprehend how truly abundant we really are. Lack of abundance of anything in your life is fundamentally an issue of low self-esteem.
If you are missing anything from your life, ask yourself: what false belief am I holding on to about myself that is preventing my desire from manifesting in my life? Anything you've ever desired already exists; the key is to live in high self-esteem and believe you are worthy of receiving it.
