What should win: sense or desires?

For example if you want someone badly and your sense is telling you not to (for whatever reason: maybe you’re in a relationship, maybe the person is a bad person etc.). What should win?
Or if you want to travel and just leave everything behind, but your sense is telling you to stay on the safe side of life?
If you’re with somebody, but you know it’s not a good idea or that it will not last, but your desires wants to stay?

It could be anything really. What do you think should win in life: our desires or our common sense?
Sense could be things like “ought to”, “should” etc., while desire could be words like “want”.

I don’t know if I described this a little messy, but hopefully you get the idea of what I mean with this question.
