By bus, by mrt?

I go to work at woodlands causeway point everyday. There's a mrt station and a bus interchange next to it so it's very convenient for me. There's a direct bus route from my home to the bus interchange but it's take about 30mins to reach. Alternatively, I can also take the bus to the mrt station near my home and take a mrt to woodlands. It will cut down my travelling time but it will cost me more on transportation. To solve that problem, i might even get a bicycle and ride to the mrt station. This will save me money in the long run... probably but i guess i'm too lazy for that.
The government has constructed all these modes of transport, and many different routes to reach our destinations. I can choose whichever i wanna take. However, none of them is straight, all are full of twists and turns. In order to reach where we wanna go, the drivers or ourselves have to look out for road signs, traffic lights, whatever signals; turn a corner when it's time to do so, stop when there's a red light or move from one route to another to cut down time...whatever.
Sometimes we take a wrong turn, or take a wrong route all together, and may even get ourselves lost or worse still, get ourselves into an accident. At this point, we always look at where we are, and the mistakes we made. But shortly afterwards, we correct ourselves, look for the right direction and the right path, and move on forward... life.
