If you are tired, it's beyond obvious you will not perform your best. You will not be bothered to think and your reactions will be sub-par.Better blood flow, more oxygen to your brains.

Having good peripheral blood circulation will also prevent freezing hands.Having stable blood sugar will help your brains to focus and avoid tired condition.If you eat a big meal, majority of your blood flow will concentrate to stomach. It is far from ideal condition. So avoid big meals after or during you play, or in other words, plan your playing around them.Caffeine is one of the stimulants you can use to keep your brain more focused. You shouldn't how ever "overdose" caffeine. 100mg of caffeine is pretty optimal. Ofcourse if you drink a lot of coffee every day, you wont get the benefit.

So not being fat helps. Im fat. Dammit.With hygiene, I mean the hygiene of your keyboard and mouse. Make sure they are clean, so there won't be any situations ruined cause of slippery surfaces.With chemicals, I mean, that when ever you do or take something mind alterning, such as alcohol or eat a lot of candy have intercourse or masturbate, your brain will be flooded with a lot of different chemicals. You can literally feel these chemicals making your thinking cloudy. Could be result of meditating.Thanks for reading and hope it was helpfull.
