Did u feel the same way...?

What is the main purpose of living and the way to lead it...? Has this question lingered in your mind, any time? I'm sure it has for many.

As of now there are two things which have been on my mind, to live a life full of content and happiness or to live a life (more a materialistic one) comparing my life with others'?? I know the former is the correct one but at times I tend to forget it and take the latter one. I would like to know how to keep myself focussed and be determined.
