A bit more regarding being lucky; with full recognition that nothing is unluckier than acting like you know how to be lucky or anything at all about luck. Even saying so is unlucky. But you guys are interested (I got a lot of email), so... I'm going to take a chance. Probably after this post I will have no luck whatsoever; (man, the things I do for you...)
Being lucky seems to involve hard work, preparation, and persistence. Confidence is good but cockiness is bad, and at no time should you rely on luck. Skill seems orthonal to luck, it can cut both ways; being lucky seems to have more to do with knowing your skill level and how you project it than the skill level itself. A sense of amazement when things go well is helpful, as is a sense of amusement when things do not.
The other day I wrote: Be one with your surroundings, go with the flow, have good kharma. Now I want to add: self-awareness is at the core of luck. Knowing yourself, being realistic about yourself, and working to improve yourself are probably the best things you can do to be lucky.
