Luck is a tricky thing. Some people have it, and some people just don't. It's not something you can buy. No rabbit-foot or horseshoe will bring you universal favor. You can waste all your money and time trying to get lucky, but I guarantee you won't be any closer to winning the lottery.
The only thing you can control in the bumpy roller coaster ride we call life is your perspective. So why not just have fun and forget about everything else?
