How do you talk yourself into something? | Psychology Today

It seems that when we talk to ourselves or others forcefully about the future, we create an expectation that we now feel that we have to live up to. If we fail to live up to our expectations, then we will feel guilty. So, the forceful “I will” statement motivates use out of guilt. When we ask ourselves a question about the future, “Will I,” then the activity itself becomes the focus. As we commit to this future activity, it becomes intrinsically interesting, and so we are more likely to want to do it.
