When someone is seen as being "determined", they are seen to have "resolve". If you look at the word "determination", you see the word "termination". Both "termination" and "resolve" refer to "completing" something or "an ending". When we say we are "determined" or have "determination", we are saying that we will take something to its full completion. We will stick to it until it is done. It doesn't mean that we will stay with it until it gets hard or difficult or boring or uncomfortable or when we lose interest in it. When we have a hard conversation with someone and we are willing to stay engaged until we find a resolution, then that is determination. Determination is what helps us persevere when others quit.
