I tend to keep either a stack of Frictionless Capture Cards or a smaller notebook (like a Field Notes notebook, for example) with me for when I’m out and about, and I use my Pilot Coleto multi-pen to write down anything in it. Why a multi-pen? Because I use the different colours to represent different things.
For especially visual people, the use of a multi-pen might be a great thing to try. As Mike goes on to say:
That way I have a visual trigger whenever I look at the notebook – I know what item is for what category. Again, the colours create a firmer connection for me.
