Yeah, I think change, you know, with like different things, like we're doing a new thing, you know, we're changing how we do things, or we're changing things around. So I think the change in the workplace, like at my security job, is one of my biggest challenges, you know, sometimes the change of things, or how they're changing things around from what they did at first, or even if one building is complete, now we have to go to the next building and patrol over there, or, you know, this used to be called a certain name, and now this is called a new name. So I think learning how to adapt to change of the work environment, you know, the different work environment.
