It is possible for the eyes to see lesser than what obtains and for the brain to interpret marginally than what is actual. This is one of the understandings derived from science overtime (from the field of physics particularly). For instance, right from my elementary days, I have been used to seeing a white tubed illuminating bar fondly called “Fluorescent Light”; my eyes see white whenever I look up and my brain interprets it to be white whenever I give it a thought. However, physics has it proven that white light is not white after all.
The Physicist says that White light is the complete mixture of all the wavelengths of the visible spectrum. This means that if I have beams of light of all of the colors of the rainbow and focus all of the colors onto a single spot, the combination of all of the colors will result in a beam of white light.
When white light shines through a prism, the white light is broken apart into the colors of the visible light spectrum. In the same vein, your true abilities as a frail mortal often time remain obscure and invisible until you are subjected to some really tough conditions – examinations, trouble times, deadlines, temptations, etc. – that would bring them to the fore. Ever heard of the story of a man who swam through a crocodile-infested river in Australia to rescue his four friends? Oh, it happened in Australia (verify http://www.theaustralian.com.au/news/man-swims-through-crocodile-infested-nt-river-to-rescue-four-people/story-e6frg6n6-1226556475251).
Only Endure! The trouble times are not there to crush you but to bring out the multi-faceted strength and abilities you possess.
Hang on! You are stronger than you ever imagined or thought about. There is more in you that has been observed by anyone, including you.
