Allowing can be compared to mowing your lawn or planting a garden. To keep your yard neat, you have to put some effort into it. But mowing the grass doesn't stop it from growing. Even if you don't pay much attention to your flowers they still bloom. There is a natural cycle of things. These cycles occur whether we are awre of them or not.
Your ideas evolve in a similar way. An idea may pop into your awareness. You may even spend a little time thinking about how that idea is useful or how it might work out. Or you might imagine what it would feel like to have that idea blossom into fruition. But without mowing, and nurturing, without taking action, your idea will be strangled by the weeds of distraction.
So let's carry the metaphor through for your success. An idea requires mowing: refining it into a specific goal or outcome. This gives you a clear direction upon which to focus.
An idea requires nurturing: specific, targeted actions that bring your idea to full bloom. Allowing means to step into the natural cycle of how things work out and to fully participate in your thoughts, beliefs, and actions.
