One True Goal as opposed to what? Several Sorta True Goals?

Yes. Multiple systems, somewhat inconsistent but serving as a check and a constraint on each other, not letting a single one dominate.

Ultimately, no matter what your goals are, you will necessarily be willing to sacrifice things that are less important to you in order to achieve them.

Not in all ethical systems.

Actions are justified as they relate to the accomplishment of a goal, or a set of goals.

In consequentialism yes, but not all ethics are consequentialist.

There would be nothing wrong with my goal

How do you know that? Not in this specific example, but in general -- how do you know there is nothing wrong with your One True Goal?
