I was going to say this, but I didn't want to be a downer on this sub, it's usually a fairly positive place.

But yeah, I think the goal in life should be to be the best version of yourself that you can.

You will very rarely achieve all of your dreams, or do all of the things that you ever wanted, because that's unfortunately not how life works most of the time, but you can learn to accept who you are and what you have achieved, given your capabilities and limitations.
