There's no real road map to L.A. Everyone's journey is different. You have to persevere and be willing to put everything in it. You have to stick it out. I don't really have a safety net, but what I do is put myself in the best possible position to succeed by working hard. Also, be careful who you let into your life.
I've done a road trip across Italy with a girlfriend, and that was very romantic. I think that road trips are probably one of the romantic things you can do. To take your girlfriend and just stay wherever; don't have a destination and just drive and see where the road takes you is pretty cool.
