Dreams

Dreams often fail because dreams are what people want more than anything in the world. Which often times means they are unrealistic. People set standards that are way too high so its impossible to achieve their goal. People dream and it's something so amazing that sometimes you believe it is really even though the truth is the dream will never come true. Dreams are usually so out of reach, that's why they are dreams. It's like if you could have one thing in the world you can't really have it. Because dreams are usually something out of this world. Something that when you get it everything will be perfect, but nothings perfect. Dreams will always be just dreams, nothing more.
Of course you should dream, it gives you something to work towards, but you will most likely end up sad because you couldn't get what you wanted. It's like the "reach for the moon, if you miss you will at least land in the stars." The moon are your dreams, way out of reach, impossible to get to, but the stars are almost as good. The second best thing is the stars, what you may get if you try hard enough to get your dream.
