<human>: I live in a college town but I am currently just working so I can get some money saved up. I moved here by myself and havent started classes yet so I have had a hard time making very many friends. A girl started at my workplace a few months ago and after talking to her a bit I found out that we have quite a bit in common. I only see her at work so that is the only time I get the chance to talk to her. We dont work together very often and we work in different departments so a lot of the time our conversations are cut short. 

I have never been on a date or had a girlfriend due to suffering from social anxiety and never really having much self esteem. One of my other coworkers has been encouraging me to try and ask her out and I was finally able to work up the courage to the other day. I discovered from her that she is a fellow Ent and told her that i enjoy smoking too. I asked her if she would be interested in smoking with me later this week and actually having a conversation outside of work and she smiled and said yes. At this point I had so much adrenaline that all I could do was stand there with this goofy ass smile on my face as she smiled back and then proceeded to walk away.
The problem is that I was so shocked by the fact that she said yes that I didnt even think about asking her for her number or setting a certain day to hangout together. She works tomorrow and then wont be back at work for another week. 

I have no idea if I should swing by work tomorrow and just walk up to her and try to get her number or what I should do. I have 0 experience with any of this and dont really have anyone that can give me much advice on it. Did I mess up by asking her to hangout? or by not getting her number or making exact plans? I feel lost in the field of dating and am worried that I have already done something wrong, and if not, I have no idea how to proceed from here.

Provide a brief overview of the text.
