My kids had it right at about 2 years old when every other word was
Drove me insane, but I actually started answering them and realized I didn't know "why" to a lot of things i'd just accepted. (ok, so sometimes I resorted to the old "because I said so!"). I'm only human. But kids see the world as new and fresh and curious. They are not afraid to ask why, as they have no FEAR of looking stupid. Now, as we grow older, we aquire that fear, so we stop asking really important questions.
In your job, do you question and challenge the status quo? Do you look at the sunset and see a new color that you hadn't noticed before? Did you have a really great idea, invention, inspiration, but just filed it in the 'stupid ideas that I'll never get to anyways' mental file folder?
I have developed techniques over the years to bring creative ideas to the forefront, but it always begins with asking that annoying question: WHY?
And then, the ideas start flowing and my question then becomes "WHY NOT?". It puts you on the other side of the fence (or the box, just to be consistent) and then Whammo!, you just became a creative thinker!
Now go file that in your "awesome ideas that i'm gonna make happen for real" folder.
