Everytime you are developing your critical sense, you get smarter (=neural networks). This happens when your mind compare things, thinkins about thinks, using visual NLP etc.

You can also buy some pills I have heard, which actually can create these neural networks. I know Ross Jeffries is taking some pills, which makes him smarter. AND he is good at some things.

Also learning to release endorphins in your body, can create neural networks in your brain. Endorphins is your body's opium. You release endorphins after everytime you have laughed a lot, made love, been out running etc. Many things that feels really good actually release endorphins... And if you are good at NLP, you actually can learn to release endorphins by command, simply by thinking of it, the right way of course.... There are many ways you can learn that.

Why do you want these neural Networks? Are you often failing at something that has to do with intelligence, since you want them? Just curious....
