In all of life's torubles, it is of principle importance to stay both positive and active. As the old saying goes, "the eye sees what it wants to see", and when one is in a negative state of mind, one only sees obstacles and immpossibilites. Of course obstacles and impossibilites exist, but they are hardly ever as determinant as we allow ourselves to believe. After all, human beings learned to fly, to reach the bottom of the ocean, to go to outer space, etc. Before any one acheived these things, 99 percent of the world looked at the problems there were for those trying to fly and simply said 'impossible.' So for our own selves, faced with what seems to be impossible obstacles, we should look back and think that much more is possible than our limited experience might suggest.
So how does that relate to positivity? The best way to beat any difficulty is always through two chacteristics : determination and creativity. Determination is the toughness, hardness of an individual that says 'one more time' even when things are bleak. Creativity is the quality of always seeing things in a fresh new light, thinking of novel solutions, and having a flexible, perceptive mind. Creativity and determination can only live off of positivity. As I wrote before, When you are negative, everywhere you look will look dangerous, difficult, and frightening. Yet, with a positive mindset, the opposite is true. When your in a upbeat frame of mind, everytime you see an obstacle in your path, ten new paths will come to mind, and equally important, you will have the motivation to keep going even when things are hard.
I encourage everyone to always be positive and work hard at their goals. I believe a world of positive, motivated people is a better one, and will make the world safer and more productive.
