origin of this subject is - that - in most of the talks, seminars and many more places, people keep coming up with the ideas. There is nothing wrong with coming up with the ideas, but the problem is that - that idea is stupid. They try to reinvent the wheel, which sucks most of the times. But on the other hand = they do not agree that their idea is STUPID - any way! so, most of the time, people try to be over creative and proven stupid immediately, I like this treatment of life with them. And this happens in many companies, your collegue will come up with a superb dev implementation - or try to write his own drivers and will understand that he is no where near some nice open source tool. So thats why he is "being creative - proven stupid"
And I think if you can avoid that - and do lateral, sincere thinking then this sentence renders itself "being creative -proven stupid"
