Why buy a Lamborghini when you can transform your body into a Lamborghini?
You are the best object to admire.
Why do we buy stuff? We want to buy objects we consider beautiful, to imbue ourselves with its beauty.
For example, we buy a Lamborghini because we want to embed and imbue ourselves with the POWER of the Lamborghini — the symbolism of the masculinity and power associated with it.
But more efficient from a money and life perspective:
Better to transform your own body into an object of beauty, power, and admiration — to admire yourself, by yourself, and even in private!
When I look at myself naked in the mirror (before taking a shower) do I love what I see?
