Its a famous saying that there is a light at the end of the tunnel. No one really talks about how to get to the end of tunnel or how long is the tunnel. Although knowing that there is a light at the end many do not survive the journey through the tunnel. encouragement has effect but it can only take you far. to adjust to the darkness of the journey is sometime very hard and you just hope that you have enough left in you to enjoy the light at the end of the tunnel when you get there. the same feelings must be for those who are in an ocean looking for shore. you know the water ends somewhere and you know there is a shore somewhere, but you just don't know how far and if you will be able to make it or not. the fear of not being able to make it is far more than the excitement of knowing that shore may be near soon. just like any other physical activities if you are not prepared and your mind and thought process is not accustomed to this kind of excitement or hopelessness, then the journey becomes even tougher. Fact of the life is that no one ideally would like to be prepared for these kind of circumstances and be the champion of overcoming these ahead of time so that's where the mystery and not knowing what is going to happen next moment comes into play. life sometime throws you in a deep ocean that sure has a shore or put you in a tunnel that sure has a light at the end but does not always tell you how long you will have to go through this. Interesting as it may seem in the beginning, hopeless it gets afterwards and boring it becomes in the end. Yet, life is beautiful.
