Man is a generalist. No harm in that: he/she is remarkably adept at adapting and to enhance this process has created a batch of tools which allows him/her to perform to the highest levels.
When push comes to shove, what are the Tools of Excellence?
1: The Notebook & Pen
Paper and ink. There it is: no power needed, discrete, ultimately flexible. On a plane, on the beach, back-backing in the Western Isles. The tool which allows you to plan, record, create, schedule, sketch and write a love note. Never be without the pair.
Which? The moleskine sketchbook. 13 x 21 cm top quailty paper. No lines; why be restricted? Super hard-back: why take risks with your greatest thoughts? Plus a Staedtler triplus fineliner in any colour you fancy.
