I've always thought the same way. History is written by the victors, but they are the ones who govern the one who keeps it in force.
The reality is that there are no good or bad things, but when we read history, we can notice that things are told so that we know who are supposed to be the good and who are supposed to be the bad.
When I read about history I try not to read the interpretations of who wrote it and to make my own, but even so, I'm just changing one interpretation for another and I'm not really reporting the facts.
So the most important thing when studying history is, not remember a couple of dates that only serve as a general culture, but to extract the information that can be useful and interpret it in a way that serves you in your daily life.
