What kind of timescale guides your thinking? Do you focus on how great things will be when you make a killing selling your company decades from now, or do you prefer not to think beyond the end of the day? When it comes to business success, choosing your time horizon really matters.
Jodie Cook completed her first start-up/exit cycle in 10 years, and she recommends it as a way of planning your strategy more purposefully: 10 years is 'long enough to think long term... but also short enough to not waste time.'
She focuses her time equally purposefully at the daily level too, working in 'blocks' to ensure the work gets done effectively and that she protects time to train and to rest - REALLY rest - in her day. And of course she makes time to write, because that's her way of processing everything.
Make time for this.
