Why daven make a bracha etc.

Do we do all of the above to please another person?
Why does it seem that people tend to think it is their business if another Davened or made a Bracha?
even if it is their spouse or other family member.
Is it about proving oneself to another?
is that why we Daven on Rosh Hashono?
I believe it is a false way in Judaism
and will try to give my outlook on why we pray and or make a Bracha and so on in the near future .
meanwhile i would just point out that if one is not in the mood of making a Bracha and so on it is no one Else's business
