My personal list: * Active noise cancelling phones and Mozart seem to help. I notice a big difference. I even don't like classical music, but it seems to help me focus better than other types of music. * Mindfulness meditation tends to help me focus even outside of meditation, especially in tasks that require sitting and thinking for >5 minutes about a problem, like maths or topcoder tasks . It literally makes me realise "oh crap, I am not thinking about the problem I supposed to be thinking". * I muted all sound notifications everywhere. Probably muting visual notifications would help as well. * Pomodoro technique * Get 100 grams of L-theanine with each cup of coffee. L-theanine is natural ingredient found in green tea. It removes jittery effects of coffee, while keeping high alertness. http://www.gwern.net/Nootropics#theanine http://www.gwern.net/Nootropics#theanine . Modafinil is good as well.
