appearances

Next week I start school and it has started me thinking... essentially I am starting seminary so what does that mean? Right now I drink on occasion, cuss when the need arises, and am somewhat sarcastic. But now I feel like I need to change.
I don’t think the change is coming from an internal motivation so it probably doesn't mean much. However, I don’t want people to look at me and say, "She is going to be a minister/pastor/whatever? But she was out with us last weekend and was drinking." But I feel like if I were to change for that reason then it would be hypocritical. I would rather be the person where people say, "Oh, that makes sense. I could see you doing that... and then go out for a drink with me. Can I walk that line? Do I need to stop being sarcastic? Do I need to stop drinking? Humm.... just some things I have been thinking about.
