This book hopes to follow in the footsteps of Edison and Da Vinci and motivate you to write down all your ideas. Make sure you do! Jot your idea down even if you think it is a mediocre one. Who knows? Sometime in the future you may develop a couple of roughly-written thoughts into a brilliant idea!
Much before I read this, I had started to maintain one for me. Earlier I was writing on paper, now its all online. Putting down all such intuitive thoughts on the internet becomes very handy when I want to refer from elsewhere. But such a list is strictly for private use only. Ok. Could you guess the tag I use to classify them?
