How to build a positive attiude

Once a men lead life by selling black red, blue and yellow balloons at the fair. Sometimes when his sales dropped, he would fly a balloon filled with helium gas. When the balloon went up into the sky, the enthusiastic children crowded near the balloonwalker to increase its sales.

Throughout the process, all balloons were sold. One day, a young boy turned his back to the balloonwalker while dragging his shirt from behind. The boy asked, "Can a black balloon also fly in the sky? Noticing the boy's excessive gratitude, the man assured him, "Brother, the balloon does not fly in the sky for color, the gas in the balloon flies into the sky." The same is true in human life. What's inside of us is the key. The thing that helps us rise above us is our mentality.
So, we all need to create a positive outlook.
