Japan has always had problems with spaces, especially in the urban areas. This space dilemma goes all the way to shelve spaces in grocery stores. Where one can see mega malls and super-duper markets in most western and eastern countries, the Japanese grocer had problems in stacking watermelons. Watermelons are round and big and consume so much space. What are we to do?, laments the Japanese grocer. So the Japanese farmer thought of growing square watermelons. Impossible! said the rest of the world. Not so as the picture indicates.
The solution to the problem of round watermelons wasn't nearly as difficult to solve for those who didn't assume the problem was impossible to begin with and simply asked how it could be done. It turns out that all you need to do is place them into a square box when they are growing and the watermelon will take on the shape of the box.
There are a lot, actually, but let me just say two things. First, Never Assume.The major problem was that most people had always seen round watermelons so they automatically assumed that square watermelons were impossible before even thinking about the question. Things that you have been doing a certain way your entire life have taken on the aura of the round watermelon and you likely don't even take the time to consider if there is another way to do it. Breaking yourself from assuming this way can greatly improve your overall life as you are constantly looking for new and better ways to do things.
Second: Impossibilities often can be possibilities: If you begin with the notion that something is impossible, then it obviously will be for you. If, on the other hand, you decide to see if something is possible or not, you will find out through trial and error.
Truly, nothing is impossible.
