For LifeHacking--instrumental rational skills--does anyone have experience getting lightweight professional advice? E.g., for clothing, hire a personal stylist to pick out some good-looking outfits for you to buy. No GQ fashion-victimhood, just some practical suggestions so that you can spend the time re-reading Pearl's Causality instead of Vogue.

The same approach--simple one-time professional advice, could apply to a variety of skills.

If anyone has tried this sort of thing, I'll be glad to learn your experience.
