how do i change?

i was asked the other day, ' how do i change?' i didn't know what they meant.
they said that when i changed my life around they really saw the change and happiness in me. they asked me how they could? i said i really didn't know.
i said you have to know what you want to change. you have to know why you want to change. i wanted to stop being a back seat watcher of my own life, so i stopped, it took a lot of will power and a little hurt, but well worth the trouble. i'm sorry if i'm sounding big headed again, am i? i don't know.
