another pop up question

went for a surf at my local beach break today, it was about 2 foot and reasonably clean, im out the back, paddling onto un broken waves like everyone else. problem is when i catch the waves i try to pop up i must be leaning to far back and im falling off the back of the board. its like stepping on a moving skateboard and it scoots out from under your feet.
thinking i need to harden up and commit more and lean forward.a few times i tried to pop up and ended in the "drop knee" position (damn body boarding habits).
suppose to be 4 foot swell tomorrow so ill be there 6am trying again. maybe slightly bigger waves will give me the thrust i need to stand tall and proud. i feel like im making progress but its only my 3rd time on a surfboard.
one other thing i noticed was youtube vids tell me when popping up to place hands flat on top of board and pop up, they say "dont hold the rails to pop up". when i have my hands flat on the board it seems to feel unstable but if i have my hands on top of board with my 2 outside fingers on each hand hanging over rail it seems abit more stable.
is their a right and wrong way of this? or just whatever is more comfortable.
sorry for the long winded posts im just full of questions and i have a thirst knowledge
