How can a person make better hard choices?

How to make hard choices was the subject of a recent TED talk from philosopher Ruth Chang. ( https://www.ted.com/talks/ruth_chang_how_to_make_hard_choices ) Her thesis is that hard choices are not about finding the better option between alternatives. Choices are hard when there is no better option. Hard choices require you to define the kind of person you want to be. You have to take a stand for your choice, and then you can find reasons for being the kind of person who makes that choice. Her views really speaks to me. In your view, what makes a choice hard? How should a person make hard choices?
