My negative thoughts are criticisms, self-criticisms, and generally being frustrated when things don't turn out the way I want.

We do have power over our thoughts. We can change them. I recently said the brain is like a muscle, not a circuit. We aren't wired, we build muscles. We can build the negative muscles (neuron pathways if you know some anatomy) and we really like to use the muscles that are strong. We're good with them. But they don't always help us and we've got to break the muscle memory and build some new ones sometimes.

I'm trying to build my rationality and build my patience, curiosity, and reading ability. I've lived in intrapersonal negativity for quite some time and it's no fun for me or those around me. If we can see our negativity and the thoughts that don't help us and think rationally about them, think about cause and effect, we can throw away our negativity when it does not aid us and start to build muscles that will help us.
