i knew someone here that let me sleep on their floor. I'm a comedian (and entertainment type in general), so I started getting on any show i could and basically demanded money (through my performance and my convo). Got temp jobs driving and doing telemarketing until i could afford my own spot. that took about 4 months. the first one was a little room with a bathroom, and bed in the wall and no personal kitchen. my kitchen was shared with 4 strangers that i never met. i kept hustling up from there.
one little hustle i had was free play. it aint a lot but it can help you with incidental shyt. casinos always have a "player's card" that counts how much you gamble. to get you to start, they always give you free play in hopes that you'll get hooked. the house always wins, you take what you win from that excursion, and move on to the next place. plus they send you coupons for random shyt like that all the time. just use em.
one spring, i was working this telemarketing job and hosting a trivia show at night. i was just barely getting by on the bus. so i went to this casino that had an extra play promotion. i played blackjack for about 4 minutes everyday, and i alwasy walked away with an another 5-10 dollars. so that's what i spent on lunch and such. for 2 months, i made back the money for my commute. you gotta be smart about it tho. dont get carried away. better yet, avoid this completely. im just telling you how i did it.
it's also possible to bus hop in vegas but that's a huge gamble. because if you dont have the dough, you're sol but its pretty easy to sneak on and save a few bucks.
tldr: i did it because i'm an ethical low life that isnt afraid of a little danger.
without a car, using a metro pcs phone, and living in an ok neighborhood, 900-1000 a month just to live. you know what your luxuries are.
