Probably you failed to the see the world around you - the beautiful people, the lovely flowers, the avenue of trees, the flowing water at a river or stillness of lakes, chirping of birds, hussle-buzzel of traffic, people who matter most for for you, the work you have, the hobbies you indulge in, the movies and songs you want to see and listen. Oh I do not find sufficient time in the day to plan all these activities and there is no room for boredom to enter here.
