I have been at the separation for a long time (I have eaten egg whites for years), but I am still really bad at it. Invariable I cannot get all eggs to separate properly. If I manage to keep the yolk intact, usually not all the white separates. For scrambled eggs, not a huge deal. but it can be for cooking otherwise, and especially baking.
I have purchased various gadgets over the years, to no real avail.
I would love to here people's tips for successfully separating eggs.
