In college, I was never one to take adderal or ritalin to cram all night before an exam. That no-sleep study route sounded miserable to me. I was the unusual student who slowly and steadily worked every single day in the library towards inevitable midterms and finals. Nevertheless, increasing brain creativity and focus through exercise, meditation, drugs and supplements fascinates me.

Evidence trends towards positive performance via caffeine, electrical stimulation and tyrosine. However, each one of these must be used properly and their effects can potentially diminish over time.
Below are links to some of the resources I've found most useful while learning about ways to stimulate increased brain creativity and focus.
