I think that line of reasoning will quickly become a ouroboros situation when you think about the details of cause, effect and desire.

I suppose the best outcome is the one where you've destroyed yourself and are replaced with a nearly identical person sans the reason you changed time and the butterfly effect of everything that stemmed from that.

At worst you've duplicated yourself and have a wonderful opportunity to observe yourself blissfully unaware of the reason you changed time.

But depending on which flavor of time travel used. I suspect the most likely outcome is you'll continue doing this again and again. Something always misaligning with your goals potentially unaware that anything has already happened. Never seemingly perfect or that time becomes this window of experience looping, endless eight style.
