What is luck?

Luck on which I never believed even I tell everyone the same thing. Let think when people say you are lucky.
1. If you got selected in an interview although you did not performed well.
2. when you got an accident and u escape from injury
3. If your flight met and accident and you escape from injury or death.
4. Now I will explain each one and describe why can’t
Say here luck exists.

1. If you went to an interview and your interviewer is also unknown of what you did. Certainly he will assume much about you. And if you explain everything and he understand a part of it. You will get selected. If a project manager is taking interview of a person seeking job then we can’t expect tat he will ask deep level questions. He will always ask generic question which everyone can answer. Also he can work with me So No luck only disability of person to ask question and his thinking.

2. Once my roommate asks me what is this helmet as this is not necessary and so there is no sense of making it compulsory. On the same day, he was coming from his friend’s house in night 1 AM. After drink with friends, he rode his bike at speed of 100 KMPH. For Bangalore, it is very much.

Suddenly there was turn and his Bajaj pulsar skated but simultaneously he press his breaks with full power He got minor accident but helmet got serious breakage. Now tell me … where was luck.
His habits of using helmet save him also. His intelligence at that time saves him from serious output.

3. When one of my friend was giving B. A. (English) paper, she use to say that I am writing so many thing but getting less marks. Actually she was doing coaching and the tutor gives notes for every question and she just write down answer and she just writes exactly tutor’s notes on paper. Also all B.A. (English) students do coaching from that teacher only. Now I tell her that if everyone will write same answers then the examiner need not to check every copy. He will just do average marking. I suggested her that writes everything in your language not bookish or tutor’s notes. In final year although she has not read notes or books, she got highest marks. Reason was that she wrote every answer in her own language even she attempt less question. So it shows that there was no luck or bad luck again. If you will go in detail, you can know what your mistakes were.
Actually all success is a group of threads. If you will make sure all thread are correct then success is sure.
