We've all thought this at one time. You're reading an article or watching the TV or just plain walking along the sidewalk and you see something new, and the first thing you think of is: "Why didn't I think of that?"
We're all bombarded with ideas on a daily basis. Most of the time we're not conscious of it, but all of a sudden you read something and then tie it in to something you might've briefly thought of days or weeks or even months ago. POW! Your idea is born.
Most people, however, are resistent to ideas. Or, they may get ideas but don't do anything with them. I talked about this before in my blog post titled "The Engine Analogy" where I say that ideas without action is like an engine without fuel. Ideas fall on all of us like rain. And, like rain, many of those people have umbrellas to ward off the ideas--they do this and don't even know it, or if they do, they do so by making excuses for why the idea won't work.
What I challenge you to do is this: when you come up with ideas, write them down. Even if you think they're stupid or won't work. It doesn't matter. These could be inventions or story ideas or even simply ideas on how to better do your work/business. After a while, you'll become atuned to recieving ideas that it looks a lot like an upside-down umbrella, where you are collecting the ideas.
Write down as many ideas in the next 30 days.
Then, at the end of those 30 days, look over your list. Instead of asking yourself how these can't be done, ask yourself how they can.
