Love?

Love...People say it's the best thing you can ever have....
Other say love will take you no where in life and have no future.......
And some say well why need love?......
Well love can be the best thing but don't good things go.........
Love can always take you to the future if your willing to take risk.................
And everyone needs love to be happy and cared about..................
But yet you repalce love with any other word and have the same answears............
So what really is love is just something says to you to make you feel cared about or do they really mean it.?
