There’s something us modellers can learn from this:
Suppose the thought enters your mind that you want to build a house. You sit down and make a list of all the materials you think you will need. Then you order them to be delivered to the lot where you will build. Everything is piled in the center of the lot, and the next day the bulldozer comes to excavate the basement and everything is in the way. It’s all just where he has to dig.
Why? A failure to plan.
Without some rudimentary planning you probably won’t have anything to eat when you get up in the morning. And without some detailed planning no one can build a house, let alone a skyscraper or shopping mall or city. If producing shelter and food and clothing and transportation is valuable, then planning is valuable. Nothing but the simplest impulses gets accomplished without some forethought which we call a plan. (Link to Article)
