Remember, luck comes and goes. It's not that lucky people feel unassailably secure--more that they refuse to relax. They keep their options open and explore new possibilities.
Don't take the blame. Lucky people don't feel responsible for their luck--when they have a streak of bad luck they don't blame themselves. Instead, they look for ways to turn it around.
Go where luck resides. Lucky people surround themselves with people who have things happening for them. Cultivate the kind of personality that gets you noticed, and then make contacts and get involved.
