From Telegraph:

The study findings have revealed that although unlucky people have almost no insight into the real causes of their good and bad luck, their thoughts and behaviour are responsible for much of their fortune.

Personality tests revealed that unlucky people are generally much more tense than lucky people, and research has shown that anxiety disrupts people's ability to notice the unexpected.

Unlucky people miss chance opportunities because they are too focused on looking for something else. They go to parties intent on finding their perfect partner and so miss opportunities to make good friends.

Lucky people generate good fortune via 4 principles:

1. They are skilled at creating and noticing chance opportunities.
2. Make lucky decisions by listening to their intuition.
3. Create self-fulfilling prophesies via positive expectations.
4. Adopt a resilient attitude that transforms bad luck into good.

Unlucky people often fail to follow their intuition when making a choice, whereas lucky people tend to respect hunches.
