I struggled with fried rice for many years before asking the owner of the local Chinese joint.
Two tips...use day old rice. This allows the rice to separate very nicely and dry out a bit.
Scramble the egg BEFORE adding to the mixture. This place actually makes it like an omelet without turning it over and then they chop it up very fine. If you add the eggs to the mixture without cooking them, they will end up binding everything together.
