The right tools for the job

My son and his mate are doing some road building on my son's property in the Snowy Mountains. The mate has his own Caterpillar D5 bulldozer which he imported second-hand from the US.
It's ideal for road building making short work of the scrub and even trees that get in the way. The cab is air-conditioned and there's a CD player and CB radio installed as well.
It's true to say that the D5 is a big boy's toy but one that's very useful for road making.
Got me thinking about the importance of selecting the right tools for the job. The D5 would be no good for a garden path or even for landscaping in the backyard.
How often do we stop and think about the tools needed for the job at hand? Selecting the right one will give you the best start for whatever you're doing.
