I'm not sure if this is what Taylor was thinking when she wrote this, but I interpret it being about prostitution.
"Every day I wake up alone" -She does her "job" at night, and wakes up alone without anyone the next morning.
"See I didn't cry when he came inside" -She doesn't enjoy her job and is just doing it for the money...she's not into it
"Drugs, bars, back seats of cars" -Self-explanatory...
"So with a wink and smile and a vile of meth, I took his hand and we walked through the shadow of dead" -She's on duty..
With the advice lyrics, she's remembering what her mother, teacher, etc. told her which could be like to get a real job, become successful..stuff along those lines.
