I am agnostic as to whether reincarnation/rebirth is a thing, but if it is then I follow the Eastern view that the best thing to do about it is to become one with Brahman/attain nirvana so that this is the last life as a separate being. I have had ambitions to spend more time and energy on spiritual practices towards this end, but unfortunately I have had numerous health problems that have drained my energy and made it hard to focus. (I also used to be in pretty good physical shape and lost most of it over the last year or two.) It would be really nice if I at least had enough time and energy to make it to stream entry in this life.
