Can I Use Four Techniques..

[Sultan]

Hello actualized society

 

I am beginner in meditation(I used do nothing technique). However,When I was searching in this  forum I saw topic about use meditation,visualization,self-inquiry and affirmation. My question is can I use these techniques together or gonna be some conflict.So I must use one.And I have small question about affirmation.Is affirmation really effect because the percentage of intelligent people in the world 0.5 . So if I said I am intelligent does this make me intelligent??!!
