How many times children hear “Do not touch the oven (or kettle, or heating). It is hot!” I, for sure, heard that a lot. And although I can not  remember the exact number of times,  I heard it constantly from my mum and by her tone I knew touching oven was a wrong thing to do. Yet my curiosity took the best of me and  one day I touched it. The oven. The very hot oven. This was the lesson  I finally learned.

It is a great way, really, to learn from our own mistakes. I mean when we conduct something successful we receive our reward proudly and then we turn  to the next project leaving the previous behind. When we commit an error, we will research the question inside and out in order to find the mistake. Have you ever tried coding? You write down the code, find that something went wrong and the code does not work, review the code, rewrite the code. Erase it and rewrite again. Eventually you get it right. At this moment you have researched all the existing coding rules and punctuation. Scavenged down a few coding forums. Learned a new coding language. All this because of one opened square bracket. How would you learn all this if you had written right from the beginning?
