The first place we lose the battle is in our own thinking. If you think it’s permanent then it’s permanent. If you think you’ve reached your limits then you have. If you think you’ll never get well then you won’t. You have to change your thinking. You need to see everything that’s holding you back, every obstacle, every limitation as only temporary.
— Joel Osteen
Sometimes however you get so tired to the point that you have no control on your thinking. You get tired while “fighting” your own thoughts.
Stop thinking so much. It’s alright not to know the answers. They will come to you when you least expect it.
