If you could offer one piece of advice to new UE4 Users...

My advice is to remember about “failure”, especially when working with game development software. You did not actually fail, you learned one way not to do what you wanted to do. Use any circumstance that was not ideal and learn from it so you can find the solutions that get the results you are looking for. When you reframe a “failure” into a learning experience way, it makes the whole process much more fun and less stressful. At very least has been my personal experience!
