Random ideas on the functioning of the brain

Our brain is capable of holding an impressive amount of informations collected through our senses (touch, sight, hearing etc ...) and we can associate as we wish these informations between them, our feelings are also stored in our brains (what makes us good or bad, what causes positive or negative emotions), it is thanks to this huge database that man is capable of creating. That is why it is important to create a database as complete as possible; babies by touching everything that comes to hand and putting it in their mouth are simply building their database. With this one they will be able to invent stories, to recognize objects in the dark, to visualize the picture of a flower just by smelling its scent, to recognize his parents by telephone.
The most complex Human creations are simply the result of a combination of informations contained in the database of the brain; scientific discoveries and technological advances always use what has been done in the past (nothing is totally originally created), man do an association of informations with the data in his brain, then tests his idea, which is working or not working but will grow the list of datas on this particular subject and every human being could use them.
For a man to be competent in a special domain he must store lots of informations on the selected domain until create "habits", the more we see or use the informations on a subject then the brain could more easily retrace the informations; the connections between neurons that allow us to recall informations deteriorate if they are not "refreshed" or "practiced", however, if the information was considered important to remember when you recorded it in your brain it will take much longer to erase. The memory of a deceased loved one remains much longer than the inside decoration of the lounge of a guy I saw two times in my life.
So, again, to be effective in an area we must create habits in order for our brain to bring back the datas much faster.
To memorize an information we must have decided that it is important to remember it, therefore we must have interest in this information, and the process of recording datas will be different if the subject does not interest us; one point which gives an interest in an information is the emotion it provokes; having an aboundant database allow to do association of ideas and thus facilitate the Learning (to be able to make a link between informations gives us an idea on a topic related to this info that we don't experienced).
So, building a large database (thanks to my senses, and analysis of it) and search for what causes me positive emotions, here is what will be my life philosophy.
