Consider all of the decisions, words, or actions we may have used this beautiful button on had it popped-up in real time.
From a self-training perspective, this button could cut-off decisions to eat, drink, think, do, or say things that would waste our health, damage our bodies, or steal time from more important priorities, be it relationship, work, physical training, or others. In a limited life span here on Earth, such a button pushed at the right times could save exponential time. That saved time could then find spot-on opportunities for excellence.
This is not just because of better opportunities found, but because we avoid entanglements that would steal yet more time from the most important things.
The cancel button in the picture is blue, a color that suggests that it is perfectly OK to cancel something. To make it red creates negative emotional associations.
Perhaps the “Send” button should be red, as impulsively or accidentally sent messages burn more bridges than cancelling messages does.
