First and foremost thing to win friends is
Be honest to your self
And do good
helping hands are better than praying lips
so based on this quote
Never harm to any one
well wish of every one
Share your thoughts,
Share your laughs,
Share your grief's,
Share your most of the possible things with the people around you
So people who comes to you are your"FRIENDS"
And remember all the people who comes to you are not your real FRIENDS
Some one might think you could be useful for those people
A true friend will be with you all the way till your last breath
