Positive Thinking is something you have to practice and work at daily. It does not come naturally to us but can make a huge difference in our life if we can do it all the time.
Thinking negatively does nothing healthy for your body. For instance when do think you are fat- it gives you a low self-esteem and makes you feel fatter than you really are. Also, our brains are not capable of understanding the difference between our thoughts and what is really going on. For instance if you think that you are getting fired, even though you’re not, your brain thinks you are so you go through the emotions of being fired.
Try it for yourself; think about someone you dearly love dying. How does it make you feel? I normally get tears in my eyes and a bad feeling in my stomach.
God wants us to have positive thoughts and not dwell in the negative, though it is hard it is something I work at daily and I hope you will too!
