Do not limit your belief to your visibility. I’ve seen people drawing boundaries around themselves just because they don’t see beyond the world and understanding they have created for themselves. Further ‘impossible’ word is derived from such mind blocks.
We tend to believe that if it isn’t visible it doesn’t exist.
We also tend to refrain ourselves from even making an attempt to widen our understanding and exposure to find out something that isn’t visible.
Further next the belief in possibility of bringing such things to surface and persuasion in executing them and making them a success. We carry more of a ‘Negative Mode’ which runs on the background of our mind. Our acceptance to what we see, what we discover and what we conceive is always on a delayed pace due to which further gaps are created.
