If you move back home, you can, will, and won't:
1. Appreciate the presence of your parents, the time is quite limited, more than you realize [will]
2. Save any money that would have gone towards rent [can]
3. Make a plan to become profitable by X date with an extended date in case you haven't become profitable. [will]
4. After becoming profitable, coming up with an amount for when you will be moving out or decide if you just want to stay and pay them a bit of rent for helping you out until you make double or triple enough to convince you to get your dream place [will]
5. Play video games all day [won't]
6. Dedicate at least 6 - 8 hours a day to working on your projects [can]
So with a good opportunity in mind, roommates can be awesome, but they are just mostly semi-friends helping you pay rent. Usually nothing more and nothing less. You'll appreciate it when you have a place of your own. I moved out when I was 23 and never moved back home again.
