I found this paragraph from Bashar to be a fascinating take on the idea that we have one life to live. Enjoy!
“The idea is as follows: you have had a saying for a long time in your society, “You only have one life to live." Well now, reincarnation notwithstanding, this is true. You, as the you you are now, only have one life to live. You’ve got one shot at being this you. Even though the soul you are may experience many lifetimes, each one of those lifetimes is unique, and a distinct expression of the overall soul you are. Therefore, since you have never been this you before; since you will never be this you again, the foundational reason for this life is, again, to fully be the you you chose to be. That’s it. Period."
