A few things that helped me fly with little help.
On the simulator make sure you can land every plane in varying weather conditions on the runway without crashing. I would fly a plane in 35 mph winds and learn ow it landed on the runway in those conditions. Have someone mess with the simulator trims when you are not looking orput tape over it so you can learn to fly with the plane off balance. When you do get your plane take your time with the instructions, double check the control throws, the directions of the control surfaces and double check the CG.
On my first solo I was at the field by myself and I planed what I was going to do and how I could land. I figured that if I could not control it very well coming in for a landing, I could have a controlled crash in some tall weeds (I landed where I wanted

)
One more thing I would wait for your first flight for winds less then 8mph.
