The tests we face in life's journey are not to reveal our weaknesses but to help us discover our inner strengths. We can only know how strong we are when we strive and thrive beyond the challenges we face.
When you have discovered your significance, your life will now begin to move towards making a difference.
In my mind, the only way to prepare for the unknown was through an internal, spiritual journey of discovery, not by calculating litres and kilometres... how can humans plan or even make reasonable assertions about the enormous possibilities life presents us?
