Any advice for someone new to construction?

Good day! I’ll be starting my first job soon as a fresh licensed REE and my role will be Cadet Project Engineer. I want to ask if the work of a project engineer is heavy or challenging, especially for someone like me who has no prior experience in construction. I’d also like to ask for tips and advice, what should I expect on site and what should I prepare for?. I’m also not sure yet if there will be a training period, but I do know there will be an orientation first. I just want to be prepared in case I’ll be starting with actual work right away especially this December?.Thank you po!
