These are nice problems to have. Most people on the planet don't have cars or decent jobs, to say nothing of lovingly nagging parents, a midterm in physical chemistry, or the prospect of a recreational sex life. One of the underappreciated arts of life is recognizing when things are good. Or you dream about graduating and getting out into the world and forget that this is probably the only time in your life for the next 40 years during which you'll be able to read about the Civil War for ten whole weeks. And here, with a fairly dashing partner of half my age riding shotgun, I was rolling along going to the dry cleaners and worrying about the med school interview, seven-page paper, and lab final that will all happen this week.
Life is good.
Luck is why I've got a pretty good squash between my ears and don't look like a troll. Luck is why I have no known allergies. Luck has brought me every good person in my life. Luck will get you married and keep you healthy and make your hard work pay off. Luck will make you crazy in a good way.
