Climbing mountains
I was once asked “you are standing at the bottom of a mountain.. you look up and see how tall it is… how do you get to the top of it?”. I paused for a second, stood up, and then started walking. “What are you doing?”. “I am putting one foot in front of the other”.
I understand their point was that they get overwhelmed. Not that actions we take must not be thought through but actions will never be taken until we put that one foot in front of the other.
