The most powerful thing that people possess is their mind. If the mind sees a host of possibilities, then that person can become anything they want to be. However if the person sees defeat, nothing can help him achieve greatness. Therefore everyone should be quick to keep their mind on positive things and not on negative things.
This is because you decide whichever direction that your life will follow. Nobody is powerless. As long as they use their mind to think on the good and not on evil. When you are busy looking for solutions, you cannot live in problems. Things will surely work out. But nobody can decide for you, you have to put your mind to it and you will achieve that which you seek.
