It's not possible to "attract them all", different people find different things attractive, and honestly I don't think "attract them all" is a very desirable predicament, better to have a deep connection with one person than dealing with many shallow connections. Besides, and I know this is a cliche by now, but repeated so much because it's true... confidence (not to be confused with arrogance) is the most attractive quality. Be healthy, sure, but ultimately be comfortable in your own skin.
