If you want your mind to expand in all different directions then turn everything else off. Yes, moments of boredom from not touching your smartphone might occur but brilliance will suddenly pop on your screen instead. Those conversations about nothing can be put on a back burner as you feed your mind with allowing it to truly think. Thoughts in which you truly have no control of them are a distraction that is as noisy as many smart phones playing at the same time so keep those voices as low as possible. Focusing on what is occurring from within in peace will allow you to expand your horizons behind your normal focus. Quiet equals creativity now seek that place in a loud world to allow that to occur.
