Think of all the cults that would form after you. XD You definitely wouldn't want that kind of attention.
This has something to do with the rewind thing, but, what if you could live your life over and over and over again, retaining the knowledge from each one before? I think that would be quite interesting...Interesting...I've thought of that. There are so many things I would like to devote my time to. Like, what would happen if I spent all my life studying only violin, or only art, or only fencing, or only piano or writing. I could develope a mastery of all of them! But if you retained the knowledge acquired before, then would you choose to pursue something else, or continue to learn more from the first? But then the world would change. Computers and technology may replace musicians, I could choose wrongly and never get the chance to be a vituoso violinist. You would still have to face the choices etc...that you would in a normal lifespan, only the time wouldn't mean as much. The idea of physical immortality and living forever is a sad fantasy. (I'm not referring to any religious beliefs. I mean...the lack of physical death)
Live your first life normal, then your next life be a genius, travel the whole world the next, learn every instrument in the world, become a pirate, thief, or something exciting. The possibilities would be next to endless...
