Thank you first of all for the nice comment left here and, yes, fear of heights can sometimes be an obstacle in reaching my goal.
Walks in nature and historical places with a considerable age are my favorites.
I sat and thought sometimes what would have happened if I wasn't afraid of heights.
Probably if I didn't have this fear, I would have had some unpleasant events, in the sense that I would most probably have ventured into places I was not prepared for and this could have led to accidents or other unpleasant events.
Have a great week ahead!
