We can say that nowadays there
are a lot of lonely people in our world.  I would like to start by saying that the problems
of finding the key to happiness are topical.  And, a lot of psychologists are able to find
the issues, where the problem of loneliness is connected with the problem of
happiness.  Personally I think that an
every person is the owner of his own life. So, by that, we need to underline
that such thing as happiness is also the part of our life, and so, it’s up to
the person to achieve it. And, if the person is lonely, it is more difficult to
him, but still, it is possible. A lot of famous doctors say the same. And, some
of my friends, that are in love say, that love isn’t the only one source of
happiness.

         However, the opposite opinions exist. And there are a lot of
people in the world saying that love is the only one way to be happy.  My sister is sure, that once she will find her
plus one, she will be happy. And also, some of scientists say the same.

         But, they forget, that there are a lot of other thing in the
world that can bring you happiness. They are friends, money, family, work and
so on. Love isn’t the only one way to be happy.

         In conclusion I’d like to say, that these statement proves,
that even a lonely person can be happy and that the loneliness shouldn’t stop
our attempts to be successful happy person in our live.
