I'm thinking about learning how to be a loan originator can anyone give me any feedback about that trade?

Basically this lady I met at work does it and makes good money at it and she offered to teach me. Well i really have no clue what I'm getting into yet. She just tells me I'm gonna have to be patient with it because I will not make the ';Big Money'; quickly at first that it does take time. Right now i work at a casino as a Table Games floorperson basically I am a level below a pit boss but one step about a dealer. I just wanna an idea of how long it will really take to learn and get it going to where i wont have to work at the casino anymore and the details of the job. Thanks in advance.
