There is a great difference between light and shadow, however, in a single instant, we can pass from one direction to the other from one path to the other, from one dwelling to the other. Everything is found in the will and in the use of discernment. Let's not lose the option of overcoming, of discovering and self discovering, of knowing the truth and of totally moving away from the lie.
In the universe, there are life and death, there are health and illness. What's needed to reach the goals? What encourages us, is found only in our conviction, nothing is reached in desperation. Everything is achieved in the constructive determination. To be positive does not mean to believe that things will happen as we want but rather is making those things happen,  achieving them. Then, all effort and sacrifice will turn into investment that in turn, is wisdom, because we are taking our life into account and making it valuable.
