Taking the Train of Thoughts....

Every now and then i will has this series of thinks that comes into my mind. And all this are related somehow. Is like taking a train, the stations are the subjext/thoughts/matter....and all is connected byt the tracks/train. And when everytime this happens to me i get frustrated easily. Since everything is related one way or another, solving one naturally would lead to solving the other. Now the problem is either dont know where to start in solving one matter, or is just too complicated that no matter how easy you could possibly think is still that complicated....getting a little confused??...yeap me too...
