It took Bruce Wayne 18 years.
It was 18 years from the time of his parents murder until he became Batman.
He had to go through:
18 Years of training.
18 years of anticipation.
18 years of emotion.
He had an idea what he wanted to do 18 years before putting on the cowl, but only after going through the training, and sensing his environment, did he fully understand.
Preparation.
In After Earth, Cypher Raige is a Ghost. A man without fear. He and his son are stuck on Earth, and although he is fearless, his son is full of fear.
When his son is afraid, when anything is out of order, Cypher tells him to take a knee and sense his surroundings. Sense his environment and things become clear.
Mindfulness.
Preparation and mindfulness are keys to understanding. From that, all things are possible.
