Explain if a person get by in life without developing an active relationship with God through prayer and receiving the Sacraments frequently.

This is a very difficult question to answer specifically
because with any question like this that has to do with people's religious practices the
answer is incredibly personal. I am sure that there are people who would argue that it
is vitally important to develop an active relationship with God through prayer and to
receive the sacraments, but the truth is that there are lots and lots of people who
don't do this and manage to survive and even thrive.

So, I
think we have to understand that people's religious beliefs and practises is a very
subjective, private and personal matter to them alone and that we cannot make universal
statements about everybody. For example, Muslims would definitely agree that prayer is
important, but obviously they would disagree with the Christian sacraments. Other
people, who don't necessarily ascribe to a particular religion, would completely
disagree with this statement. Therefore you are only going to receive a personal
response to this question.
