That's the thing...it's called a plan.  Get into a shelter so that you can take shower daily.  Get job to start a savings.  Save up (and not waste it on booze or drugs or pets or whatever) and have a plan to start renting.  Then, while renting, have a goal to save up so you can buy.  If not here, buy elsewhere.  
By the way, the ones hustling isn't the ones over at Kakaako and Nimitz.  Go drive by Nimitz, some have nicer cars than me!  So don't tell me that's from dumpster diving.  They obviously have "wants" overtaking their "needs".
