In my experience, I find the best way to come up with creative ideas is when I try not to think of coming up with one.
A lot of my best ideas come from simply living my life and having lots of ‘me’ time.

The Google offices actually encourage this by allowing their employees to spend an ample amount of time taking part in fun activities.

I would say the reason why this works is because you’re allowing your mind to ease by engaging in things that aren’t directly related to what you’re trying to do, which is coming up with a creative idea. If you simply let go and have faith that your mind will come up with a solution subconsciously, it will eventually happen.

Maxwell Maltz in his book ‘Psycho Cybernetics’ refers to this as the ‘success mechanism’ 🙂
