Answer:
It sounds right.
Step-by-step explanation:
I just have a few tweaks, try this instead,
I strongly believe that believing in yourself is something very significant in life. If you believe in yourself, you will feel very empowered about yourself and most definitely confident. It not only helps your mind but your body as well. If you don't believe in yourself, the result is quite the opposite. You will feel bad about every situation you are appointed to and your mind will never get to try new things because of not believing you didn't give it a chance. I truly believe that it is dominant to believe in yourself every time that you can and tell yourself that you are capable.
