By doing so in your dreams. To be taken seriously by a landlord as a tenant you need to prove you make 3 times the monthly rent, and selling your plasma just doesn't pay that well.
Edit: I apologize for being so flip. It's pretty clear you don't understand how renting an apartment works, nor understand how lying isn't the way of life you seem to think.
When you rent an apartment you need to show you make enough money to afford the rent plus all the other things you need to pay for like: food, taxes, insurance, utilities, entertainment, car/gas, etc. so the landlord often requires you to make a lot more than the amount of rent. In addition they tend to not rent for short periods because it takes too much work to prep for new tenants so often. A tenant also needs to have good credit and when you are first renting, you tend to not have any credit much less good credit. So, you need someone to guarantee the lease, often known as co-signing. Or at the very least have people who are well respected give you a reference to say you are a good person too. But if you are demanding people to lie for you, that doesn't make you a good person.
