"You get what you think about whether you want it or not" Abraham
"If you want something to dissipate, don't talk about it. Don't discuss it. Don't bring it up. Don't think about it."
You are what you think, definitely not what you eat, but that's another blog.
The thoughts that keep you up at night, robbing you of your beauty sleep, they are exactly what you are drawing to you.
The disagreement with your brother, the critical performance review, the entire family dynamics of the moment, anything that you are constantly mulling over, obsessing about, and talking about is manifesting into the life you are living.
"You want to begin to pay attention to what you're saying yes to and say it more often, and what you're saying no to and say it less often because you get what you think about whether you want to or not." Abraham-Hicks
Don't allow your stressful thoughts to dominate your life, it is a waste of time to worry or stress and it will manifest into illness. Concentrate, instead, on whatever makes you happy, fills you with joy, and delete the thoughts that don't.
"Find something that makes you happy and think about that." AH
