Books about these particular topics... (more info inside)

[student_psy]

Hi. I've been interested in psychology a lot lately, I don't have practice coz I do not go out a lot. So anyways, I wanted to read some books on these topics, I don't care about the price or whatever:
1. influence on people (possible ways, theories and all that), like... How to talk somebody to do something, like changing his or her habit or habits or lifestyle or something like that. change his or her thinking about something, in other words...
2. changing personalities: might sound crazy but a good friend of mine is somewhat changing and so i would like to read about why and how the personalities can change, what can influence the change. he is becoming like more social, extroverted, having less values and all that...
3. self influence: when somebody is telling repetitively something to themselves and it makes them believe that it's true, even though they know it isn't, or they are preventing themselves from doing something or whatever like that. it'd be interesting to read what are they experiencing, thinking, doing. what would trigger such things to do and what would trigger the opposite reaction - dropping all that self-influencial cover and go to the thing you believe is right.

Could anybody recommend any good books on these topics? I don't care about the price or anything, I just need them to have an English version, and I'm okay with that. Thanks!

"Personality, Individual Differences and Intelligence" by John Maltby, Liz Day and Ann Macaskill

An academic approach.  Cannot think of a casual approach book.
