make an impact on someone's life

So, I’m not talking George Bailey impact on someone’s life, that’s a bit extreme. And I’m not talking about the normal everyday impact that you have on your friends or family, everyone does that. Somewhere in the middle would be good. Where something I was able to do or say had a positive effect on someone. Where it changed their way of thinking or changed how they see the world.

i don’t remember the tune

but the message was basic:

“i’ll never forget you.”

i want to affect many people’s lives.
