While most of us have a system capturing stray ideas as they come up over the course of the day, it can pay off to put aside some dedicated 'thinking' time, according to the Lifehack.org blog.

You'll need to put aside time to be alone, somewhere quiet, with pen or keyboard close to hand to take notes.
There were a couple of particularly useful tips - one being to go for a walk, the other being to drive and park your car somewhere quiet.
