[Bourne Movies] What part of Operation Treadstone turned Jason Bourne form elite solider to the superagent he became?

Like what were the training methods the book or the movie said that bourne went through physcologically? What caused him to get the migranes and light sensitivity? I didn't understand how he turned from they turned him form this good human fighter into an agent who never made mistakes, always focused on an objective, and had the mental strength to do whatever he needed.

Ok so book bourne and movie bourne are so different its really not worth comparing. In the movies, it is shown that Jeremy renners character in the 4th bourne takes the different drugs to enhance his natural abilities. Ive only seen that movie once but the implications were that this was used on all the "assets" to make them better. Plus there was extensive training w treadstone on how to be an assassin. The reason behind it in the books is a whole seperate issue, totally way better story, so i wont spoil it if you want to read it. If not, let me know.
