@ spank: You know, sometimes just reframing a situation and changing one's perspective can do a lot. For instance, maybe it's not so much that you're plagued with bad luck; maybe you're just keenly attuned to mishaps and the like. To be fair, you can't really rush through doorways in darkened rooms without expecting something to happen.
We are - all of us - full of mistakes. I personally think learning to laugh at ourselves is one of the wisest and most freeing things we can learn as we get older. Some people seem to move through life more gracefully, and maybe they do. But we ALL have skills, talents and luck unique to us and our circumstances. We just have to listen closely and fall in line with the rhythm of our own music.
Like you, if there's an obstacle I'll hit it, a step and I'll fall down it, a low-hanging item and I'll run into it. I don't win contests or games of chance. I've never been "picked out of a crowd" or had such luck befall me I couldn't believe my good fortune. But I have a different sort of luck. I've had to save all mine up for a few truly threatening situations in which the outcomes were decidedly undetermined. My personal luck is saved for survival, and I'm okay with that. They can keep their free cookware and I'll invest in Band-Aids.
You only need to find your luck. Try not to be resistant to it. Luck and good fortune float through the air; but you have to believe you're allowed to reach up and grab some for yourself. You deserve all the goodness the universe has to offer, just the same as anyone else. Next time you find yourself lamenting your bad luck, ask yourself what small lesson has just presented itself to you as a gift. Good luck, and take it from me, wear shoes; enough broken toes will teach you a thing or two.
