I hope it doesn't come as too much of a shock: Both of these sayings are much more myth than fact. Beauty is, in fact, quite objective and measurable. Trends and small changes in preferences come and go, but core aspects have remained the same throughout the world and throughout history. In fact, research shows that human beings have evolved universal standards of beauty, both within and across cultures. Hint: Much depends on the symmetry of our facial features, our waist-to-hip ratio, a mathematical principle called the Fibonacci sequence, and some other choice factors.
You might not consciously know how these particular details make beauty quantifiable, but your brain sure knows them when it sees them. When we spot a particularly attractive person, somewhere deep in our reptilian brains, a beauty alarm goes off. It tells us when we've struck gold, and it does so automatically and subconsciously. Just like a reflex, it's impossible to stop—and it's Annie Oakley accurate. Your beauty detectors have the mathematical precision of a Swiss watch, and they're rarely wrong. That's why outer beauty is nothing to take lightly. The good news? You can influence it to a large extent.
So you can also forget the adage "You can't turn a sow's ear into a silk purse." You're already beautiful. You wouldn't be here unless your ancestors were beautiful. You need to accept the fact that we're all beautiful; sexual selection guaranteed it because your ancestors mated with the most beautiful partners. We all have beautiful elements in us. You just need to use the right strategies to maximize them.
