It depends on what we're talking about. My number one motivator is providing for my family. But I also don't like change and I have strong internal motivation, so I naturally resist giving up on things almost to a fault. I tend to remove emotion from decisions and I hold myself to high standards, which helps me stay committed to my convictions even under peer pressure or without external validation. If I believe something is right, I'll stick with it to the end rather than do what I see as wrong; even if there's a big gap between what I think is right and what others think is right, I'll stick to my convictions in the face of 'adversity' (which manifests differently depending on what we're talking about, which is why I mentioned it at the start).
