Sometimes all you need is space to think.
Short of travelling to those vast open spaces, having a simple, uncluttered space will do it. A place for breathing and getting your mind blank.
When all around you is busy, noisy, full of things competing for your attention, a simple, empty space means a way out.
Even for a moment.
Keep a room, or a space empty. Maybe add a thing or two that will allow your mind to wander free.
Bare walls enable the imagination to flow. Empty rooms invite air and quiet in.
If nothing else, just maintain clean, empty surfaces. That alone can help.
Start by selecting a space. Then empty it. Keep it clean, keep it bare. That's your out.
Make it a habit.
