Weeelll, it can get a little tricky. When we were drinking we WERE trying to make ourselves "happy"--and often at the expense of other people.
But in sobriety, although sobriety comes first (because without it we are no use to anybody), we have to start putting other people's needs (not necessarily their "wants" but their NEEDS) ahead of our own immediate gratification.
Sometimes it's difficult to sort out our motives and whether what the other person wants is reasonable. That's where a sponsor or other objective, sober, third party can be helpful. We have to take care of ourselves, but not simply indulge ourselves at the expense of others.
