Yeah IMO living as a dude entails passing. You can't live as your real gender if you don't pass most of the time.
When I transitioned and began living as a man, I dropped out of school, started binding, packing, lowering my voice, and using rogaine on my face. I rebelled against my then transphobic manager at Arbys by refusing to wear my legal name on my name tag (lol I don't recommend this but it didn't matter in the end) and eventually got fired/left and never came back for unrelated reasons. This was good though, because I later got a job at Burger King where they accept me as any other man there. I couldn't have lived full time as a guy if it weren't for having some male characteristics already...by male characteristics I mean huge feet, male body language, etc. I never bonded with girls at school but didn't bond with males either, so I was pretty androgynous in personality...it only took some subtle physical changes to affirm that I was a male (haircut, clothes from the men's department) I also couldn't have transitioned at all if I'd stayed in public school. Often to have a successful transition it's required to start over, luckily for me there wasn't much to leave behind and everything to gain. I wasn't happy with my life until I transitioned. There wasn't much of a life for me to leave behind when I left school and started over. I don't regret it a bit. I'm not on T, can't change my name for another 4 months...but I'm living full time as a man. It can be done...it's how most of us start out actually. But it takes guts.
Looking back I realize I acted headstrong and stubborn at times..but it paid off. I wouldn't advise screwing yourself out of a job in transitioning as I did..in my case it just turned out for the better.
