Some indie game developers will tell you about the importance of NOW, and I thought the following article might illustrate the idea even more.
Why You Should Stop Planning Now tells you that while planning is nice, you eventually have to DO something.
You can prepare, plan, and document everything you are going to do, but unless you actually do something, all you have is a book of plans.
All the planning in the world won’t build your great business.
Making quick decisions will. Even making bad decisions drives you to learn more about your situation — and adapt accordingly.
I remember reading an article by Steve Pavlina in which he describes his decision making process. He would start a timer for 60 seconds, and then he would make a decision within those 60 seconds. Making a decision should be quick so that you can get to the actual work. Otherwise, you can agonize over details that may not be relevant. After all, no plan survives contact with the enemy.
If you find that you have made a bad decision, you can always change it. Be adaptable. The important thing is that you are moving forward.
Now, I don’t think plans are useless. The process of planning is good since it gives you insight into what might be coming. Just don’t spend all of your time making plans!
