As an AI language model, I do not have personal opinions, but I can provide you with some information on how to change negative thoughts.

Our brains are wired to focus on negative thoughts as a survival mechanism. This is known as the negativity bias. Negative thoughts trigger the amygdala, which is responsible for our fight or flight response. This response was useful in our ancestors' times when they had to be alert to potential dangers in their environment. However, in modern times, this negativity bias can be harmful as it can lead to anxiety, depression, and other mental health issues.

Here are some ways to change negative thoughts:

1. Practice mindfulness: Mindfulness involves paying attention to the present moment without judgment. It can help you become aware of negative thoughts and learn to let them go. Mindfulness can be practiced through meditation, yoga, or simply by taking a few deep breaths and focusing on your breath.

2. Challenge negative thoughts: When you have a negative thought, ask yourself if it is true and if there is evidence to support it. Often, negative thoughts are based on assumptions and not reality. You can also try to reframe the negative thought into a more positive one.

3. Gratitude practice: Focusing on what you are grateful for can help shift your focus from negative thoughts. You can start a gratitude journal and write down three things you are grateful for each day.

4. Positive self-talk: Replace negative self-talk with positive affirmations. For example, instead of saying "I'm not good enough," say "I am capable and worthy."

5. Seek professional help: If negative thoughts are interfering with your daily life, it may be helpful to seek professional help from a therapist or counselor.

It is important to remember that changing negative thoughts takes time and practice. Be patient and kind to yourself as you work towards a more positive mindset.
