I think Youāre Right.
Well, if we try to imagine/view things from āan outside perspectiveā (Gods perspective or anyway, outside time-space), then itās all like a Movie really, the difference being that the movie is constantly changing, constantly adding new possibilities, new past-present-future decisions and events; if we imagine time like a line, I think the best way to imagine it is like a snake or a wave, always moving/waving itās body (past-present-future) - Idk, this is an Analogy that Iāve lately had in my head.
My own opinion is thst itās not worth it, I mean, you from the past or you from now or from the future, itās still YOU, same with different time lines, itās Still You - however, if You think itās Worth it, Nevermind my opinion.
I mean, being rich or being poor, being healthy or sick are Quite Different, from our human perspectives, yet, theres a question: Why did Your Higher Self Gave You This Timeline?
Maybe thereās work to do here.
(or maybe not lol - You Know Better about Your Life)
Also, we have this problem: if Karma is ones own doing, then arenāt the bad time lines also our own doing?
Maybe Your Higher Self Wants You to Learn Some Things āHereā, in order to generate a Better Future and a Better Timeline by Learning from mistakes and Improving, by mending your poor timelines. (?)
