The simplest of the problems can lead to the greatest of the innovations. As children we used pencils a lot. The only problem or problems was the sharpening the pencil and the protecting the nip part from breaking. of course we had a chakmar (Sharpener for the uninitiated) but it was borrowed and was never returned. We struggled our entire childhood without a solution.
But a solution was invented and what a brilliant solution it was!!.
The eyebrow pencil makers came out with a solution. They designed the cap of the pencil to be a sharpener. What a breath taking solution to a complex problem. Three issues were tackled at a time. The pencil could be sharpener, the nip would not get cut or broken and third the eye brow pencil as it was sheathed would not smudge and spoil the ladies handbag. 10 out of 10.
Opportunities are just waiting behind the curtain called the problem. Open the curtain and Voila there could be a opportunity of a life time.
