Sorry??

Kabhi Kabhi mere dil me khayal aata hain...song running in the background in the cab....I was thinking about the word 'sorry'. I realized I use that word more than once everyday. I already started the day with a sorry to cab driver for making him wait for half an hour. Questions in my mind:
1) Am I doing so many mistakes that I have to be/say sorry daily?
2) or am I using it even if it's not required?

Answers?

I was wondering why there would be seven and only seven wonders on the earth, reading about ancient/modern seven wonders during good old kiddo days. I still wonder. I believe earth has innumerable wonders.

Introspection?!

He criticises every action of his. He questions himself every minute. He feels every work he does should have been done in a different way. He is afraid people are observing his every action. He knows he did not do anything wrong. He is under so much of inner pressure. He is no more happy and too much of introspection is affecting his health, relations, work and what not.

He hasn't yet realized being happy is the important thing in life after all, irrespective of what you do and how you do.
