Hi!The answer very much depends on YOU.
For most people, the answer is no. As the saying goes, 'No man is an island'. We need emotional support. We want to be loved. It is almost impossible to live alone, with no family or friends and still be happy.
Having said that, I don't go round making lots of friends because a lot of people are a waste of time (those with agendas and motives especially) but I do focus on a few true ones. People whom I know I can count on, in times of need. And I will do the same for them. For me, that is enough.
