To advertise yourself as both smart & sexy is not only narcissistic, it is also inefficient and tacky. It makes you look greedy; and ultimately foolish. Also, it is the easiest way to be misunderstood by your awfully heterogeneous „target audience”. By playing both cards at once, you will not only lose both, but you will also live to see both qualities turned against you.
Sadly, all unwise women religiously believe in conventional wisdom, therefore most unwise women force themselves into the limelight by recommending themselves through trendy clichés, like smart & sexy.
Nobody told them that managing such (supposedly) dangerous attributes is solely a matter of self-control; and that self-control is solely a matter of true wisdom.
And so a wise woman knows that being considered smart & sexy is irrelevant to the two vital questions: „will I ever get laid?” and „will I ever get a Nobel prize?”
If you feel you are smart & sexy, go home and work on your greed level. Those dudes from the Royal Swedish Academy of Sciences cannot handle a woman like you. Not just yet.
