How to have brains like Albert einstein?

Although of average size, Albert Einstein's brain had a larger parietal lobe and a smaller groove separating the lobe, possibly accounting for his genius at mathematics, or possibly coming about because of his continued thinking process {source from http://www.encyclopedia.com/doc/1G1-56249888.html} .. I would like to ask what type of mind engaging activities can we do to achieve brains like einstein? what type of critical thinking?
