1). A means of improving magical methods by acting as a record of experiments;
2). A goad to further work (there’s nothing quite like a blank page to give you a kick up the arse);
3). A method of integration;
4). The provision of a better record than your memory;
5). The diary renders predilections explicit, either as an indicator for specialisation or high time you tried something new.
