Let God control your life and mind

There are days when you think it’s the perfect day.
You are happy with what you are doing.
You already felt the peaceful surroundings.
But all of a sudden negative thoughts will appear.
You just think about what you will do tomorrow.
If tomorrow you are still happy.
Whatever you can think of. Suddenly you forget the joy of the day. Because of the negativity in your head.

The only thing I did to get rid of the negative thinking was that I prayed and let God control my life and mind.
