Another way to increase your luck--a method that many people swear by--is to employ the Law of Attraction in your daily life. Whether you believe that it will bring you everything you wish for, or you just expect it to clarify your goals and work harder to achieve them, it can be an effective tool for going after your dreams.
A third way to feel lucky in your life is to focus on maintaining an attitude of gratitude for what you already have. You may find that you feel quite rich and blessed already, in ways you didn't realize before.
All of these methods can help with stress management, and all are simple, effective ways to feel lucky in your life. And they're all better bets than chasing down the magic, wish-granting unicorn of my childhood daydreams.
