As others have said - addiction will be your main problem....
As probably the least experienced PPL wannabe here and therefore the most qualified to answer your question (
), without knowing what pitfalls you expect the best bit of advice that I can give you is to relax!
I've found that in any given situation where you feel a bit nervous, the best thing to do is to take a deep breath and count to three. Last weekend, I started circuit bashing and did my first solo flyaway and when I came in to do my first landing there was a bit of a cross wind. I had the usual "death grip" on the controls, so I literally took a deep breath and slowed myself down....
Worked a treat.
