Immaturity

I've a colleague who says he rarely uses the term "immature" because it sounds so judgemental.  Rather than that term, he tells folks that if they are primarily focused on the now, their feelings and themselves then they are likely to make unhealthy choices--unhealthy choices as in immature.  Certainly we need to pay attention to the now, our feelings and our self but these need to be filtered.  A preoccupation with whatever is happening now could be filtered through a consideration of consequences.  What might be the future implications of what I'm thinking about doing?  Feelings need to be filtered by thoughtfulness so that we can determine if, how, when and to whom we might share those feelings.  How could I share my feelings so as to help the present situation?  A focus on self could be filtered through a consideration of others.  What would be the implications for my family, friends, colleagues, etc. of the actions that I'm considering?  I've encountered too many folks who get themselves in difficulties and cause unnecessary problems and grief for others because they insisted on doing whatever they felt like doing at present and they thought their behavior affected no one but them.  That sounds like children who are expected to be immature.
