What you have said is the reality of your life. I heard this saying a long time ago, and I still believe it is true, and it will affect your thinking and your behavior.
If you have a negative thought in your mind, and you say some negative things related to that thought, the negative thought will be reinforced, and eventually the negative thought will become a negative thing in the future. So everything around you will be negative.
I heard another saying that If you believe it, you will eventually get it and see it. If you don't believe it until you see it, you'll never see it, and you'll always be a loser.
