A life journey?

I've always thought life is like riding in a train. i've heard this from somewhere before....think it's from a television show but never mind...it's the logic behind such a saying that made me ponder a lot.

yeah...i guess life can be described as such. since your entry into the world as a naked crying baby, u have embarked on your life journey. it's like traveling on a train, it's just that u don't know where your final destination would be. it's like sitting on a train, not knowing where u want to alight until something happens that triggers your intention to alight at a particular station. if there is no such trigger, then u would only wait till the end of the ride and see what's in store for u.

the people that u meet, the things that happened in ur life are all stations that u have to pass. sometimes something happens that made u want to stop and alight at that station. for example getting married; u alight at the station and bring on another passenger and continue on ur train journey. but there are others that made u alight at that station but never could u board the train again. this is akin to taking drugs (alighting at the station) and dying from an overdose or some other diseases contracted from the sharing of needles (never being able to continue your journey). thus alighting at a station is almost like a commitment and u almost always have to consider if u will ever have the chance to board it again or catch the last train.

sometimes when nothing exciting happens in ur life, u may just go on with ur journey, not knowing where the train will take u. of course, in the real-world, u always know the final destination of a train. but for a train on a life journey, you would never know where its final destination would be. would it reach a beautiful place with a landscape of rising mountains and peaceful rivers, or will it reach a sinisterly dark place where no amount of light could ever brighten the place?
