There's the hustle of always asking, of putting yourself out there, of looking for discounts, shortcuts and a faster way. This is the hustle of it it doesn't hurt to ask, of what you don't know won't hurt you, of the ends justifying the means. This hustler propositions, pitches and works at all times to close a sale, right now.
This kind of hustler always wants more for less. This kind of hustler will cut corners if it helps in getting picked.
Then there's the hustle that's actually quite difficult and effective. This is the hustle of being more generous than you need to be, of speaking truthfully even if it delays the ultimate goal in the short run, and most of all, the hustle of being prepared and of doing the work.
It's a shame that one approach is more common (though appropriately disrespected), while the other sits largely unused.
