I eat out almost every day. Why? Because I like spending the extra money? No, of course not. What’s sooo important for me in life is creative energy — feeling creative and actually being creative. Basically creativity is fed by change of context, changing your situation or environment. IMO one of the simplest and most effective ways to do this is to move around; go out for lunch, interact with different people and get into slightly different situations than you’re used to.
