Sawmill work opportunity

So i am tired of working with mdf and plywood at my job, I applied to work at the local sawmill/ lumber supplier and was asked to come in Thursday and shadow and check it out. I was so excited, but must admit, I’m a little nervous. I’ve never used commercial equipment like they have. I’ve used a small jointer before and some thickness planers but none on the size and scale I will be doing here. They also use a straight line rip saw and wide belt sander which I have never used either. I know I will like it way more than my last line of work, even though it seems a bit more laborious, but I’m so eager for change and interested in wood and woodworking that I think it will work out. Wish me luck
