Regret as a feeling

I had two clients today that had regret as a feeling that caused actions of wanting to do better, be a better version of themselves.  But regret does not feel good and I feel we can only sustain that for a time. So I talked about having their own back, the option of moving to a place of compassion when regret is no longer serving them.

I guess it feels confusing because it is a negative emotion creating positive actions.  I feel that those same actions can come from a more positive place, so I coached that way.  Just looking for feedback or another perspective on this.  Thanks.
