What does this entail? Well, there are three basic parts to this:
- Build a strong "network of luck"
- Have a relaxed attitude toward life
- Enjoy new experiences
Well, to build a strong 'network of luck', you have to go out, meet people, and be interested in them just for the sake of meeting people. Extroverts tend to be lucky. They meet a lot of people, they talk a lot, and when they meet people and talk to people who can help them, they manage to make the connections they need.
The Relaxed attitude toward life means you're a) open to spur of the moment or new things, and b) not too wound up when things go wrong. You don't hold grudges, you're not neurotic about what people think about you or what the future holds. You roll with it. Go with the flow. You have a goal, but the route is open.
Enjoying new experiences gives you the means to try different things, take (responsible, moderate) chances, and being open to finding something new that you love.
All of these things help you to increase your luck. New things and new people bring new opportunities.
