I think it is great that someone wants to make a change for the better, it takes sheer determination, strength and courage to make changes.To be helped along the way, you should have a support network  that can keep you motivated and focused.

Everyone can benefit from positive reinforcement but changing a person is difficult....

Yes but one cannot change others only themselves.

It would be VERY NICE to see someone change his/her life and get on a good path, secure a terrific job, marry "the one" .  What I have learned the hard way is that I cannot change someone. People change when they are ready to change. Helping them, as far as I am concerned, is done with encouragement and mental/emotional support.   It may seem my answer is cynical, which it might be.  There are reasons for it, though.   
 

Why does one feel the need to change a person?

HMMMM.........sounds like an insecure person who would do that.

Sorry if that sounds rude,  but that is the start of a massive war between you and the person you want to change. Get a life and let the other person get theirs.
