Life of a Hero
Hero is actually a term that we define ourselves based on our mindset.

For example, a football fan like me thinks of the Lionel Messi like a hero because what he does is extraordinary in my eyes. A son/daughter may consider his parents as heroes. A lover may consider his partner as hero and so on.

In real life, every body is human but what makes him a hero is how we idealize him. One cannot be a hero in eyes of all because everybody has different sets of idealisation. A hero for me may be commoners for others and vice versa.

The hero for me would be -

The one who has given his life / her life to something bigger than oneself.
The one who finds the strength to persevere and endure in spite of the overwhelming situations.
The one who can sacrifice his life for the welfare of others.
Heroes are the people who inspire and gives us the strength to face dire situations in our life.

A salute to heroes !
