Has anynone managed to make the "hyped self" become a "normal self"?

Yesterday I read a post where a dude mentioned that he approached a girl, I don't remember he got the number or not. The point is, he said he "went hyped" and felt confidence and drive inside in the following several days. But in the later days he didn't take actions and lost the hype and changed back to the "original self".

​

I have a similar experience. I wonder if anyone managed to make this hyped state become a normal, constant one, and how long does it take.
