Just take it easy until towing becomes second nature. Be very careful around corners/signposts/trees and such. Even after 10+ years of towing fiver, I still get too close to curbs and don't fully watch the trailer around corners.
The rest is all on-job-training and can be part of the fun if you don't have an expensive lesson...
Welcome to the forum. What fiver and tow vehicle?
