My opinion only but to me flying with Safe is nothing more than letting someone else fly your model.

Like Jester said, "proper goal setting is the key."
Establish your goals and pursue them with practice, practice and more practice. Under the eyes and hands of an instructor if you still need one. And being able to fly more than just a circuit is important. Full size require cross country flights for their tickets. Our equivalent is to fly different directions and handling basic maneuvers like loops, rolls and stalls. "Nice landing! Can you do it from the other direction?"
