The things we see being created were once an idea. And they did not form until certain things happened. That certain things is starting and being about it. What we mean by it depends, but it’s usually the work itself.
When you work, you come across things that are not expected if you’re still in search. That’s what we miss out on when we don’t start. There’s got to be something going on for it to be something even bigger.
You can’t determine if your idea is horseshit or not by doing nothing. How can you expect to have the expertise or even knowledge when you don’t even get the feel of it?
