OC is about the journey mate, not the end point. And that is something folks do not get big time. The journey is about getting to know your system, your components and how they all fit together. Change one and you have to re-learn all about your system all over again it seems. OC is about never reaching a plateau of knowing, because there is always something more to know to learn to invent at times if you are pretty smart or lucky.
🙂It is a journey not an outcome.
To help us help you - please provide as much information about your system and the problem as possible.
