Everybody wants to be intelligent, but no one wants to develop it. Intelligence is made and it is not something you are born with.
For some people, the ability to be social and recognize social situations and act accordingly is Intelligence.
Intelligence is knowing how to get wealthy for a person who wants to dwell in luxury.
Intelligence is knowing how to get those six packs through diligent exercising.
Brain power is very subjective and you have to have your own definition of that. And you may have more than one definition across different areas of expertise.
One of the most generic form of brain power is called Presence of Mind.
And like any other brain power, it can be cultivated.
And here is how it can be done.......
1. Have more experiences
You cannot sit in a room and think your way through life. You have to experience Life to live it with a heightened sense of being alive and hence with good brain power.
2. Get as many perspectives as you can
The more perspectives you get, the more your thinking capabilities.
3. Never have an Ego that you are above all no matter how intelligent you are
I think this is the first step anyone should have to cultivate your so called, "Brain power". The more empty you think you are, the more you will be filled.
4. Stop thinking of trying to cultivating brain power all the time.
This quote from the movie Knockaround Guys says it all.
"500 fights, that's the number I figured when I was a kid. 500 street fights and you could consider yourself a legitimate tough guy. You need them for experience. To develop leather skin. So I got started. Of course along the way you stop thinking about being tough and all that. It stops being the point. You get past the silliness of it all. But then, after, you realize that's what you are."
It stops being the point. And on one fine day you finally realize that you have so much Intelligence and brain power.
