A question he had, what can be harder, walking to the unknown or staying in it?
The answer depends if the present is satisfying and if he is an adventurer. I would walk to the unkniwn. Afterall, life is about exploring, gathering experiences and not wasting time out of fear and lack if courage
You gave an answer that covers more than one view. You know what they say, "man fears most what is not known to him". Yet, exploration is part of the journey.
That is how I see it, but I know most don't. They even prefer to be molested instead of leaving and starting new. It clearly takes courage to get the best out of life and know when a border is crossed and say: No, it's enough.
