If life gives you lemons make lemonade. You should start thinking from another perspective and you will see that the situation might be not as difficult as you thought.
That's right. We should learn to embrace what was given to us, that would make you positive in life. However, if you have nothing to it, it doesn't mean you'll love it and just wait til someone arrive and help you.
To be positive, well just stay away from negative people, it is contagious, sooner or later you'll be like them and become emotional too and then you'll spread the same.
