Why this works:

1. You don't stuff your living space with nonessential possessions.

2. You are flexible and resourceful.

3. You have organized your time as well as your space and developed the habit of putting things away as soon as you are finished with them.

4. The rest of the life you want is right outside your door.

Other commenters suggest your youth is a factor. I disagree. My old bones would have a hard time sleeping on a futon, but aside from that, the only thing that would stop me would be all my books and kitchen gear that I imagine I can't live without.

In any case, kudos to you for knowing what you want and figuring out how to have it.
