One of the basic understanding is that the moment you've molten the core the flux is gone. So just taking an iron and prodding something or even worse pushing hard on it, gives zero results.
Some flux has to be always molten in. Otherwise the solder gets instantly oxidized and you get nowhere. Just the basics. If you know the basics you can't screw up. Any time you are applying any kind of force, you are doing it wrong.

if you want to learn to solder, get some prototyping board and some 555's and LEDS and stuff, maybe a little kit with different resistors and capacitors, then build some little circuits. Get good, with your results actually working with new parts before attempting repair work.
