Rent by room or floor or whole house?

I just recently closed on 4 bedroom 2 bath house. First time house hacker. I can actually be convert another room into a fifth bedroom with just a wall.  I would stay in the fifth bedroom. I was wondering what would be the optimal route to go.  Should I rent out by each room?  I could rent out the top floor (2 beds, 1 bath) or the bottom basement (2 beds, 1 bath) as well?  I'm trying to figure what would be the most optimal vs. most profitable.  Am I flying to close to the sun on this?
