If I didn't Believe where would I be?

When U look back on your life, it seems thats when we realize our mistakes and faults.

But isn’t that too late, isn’t that pissing your life away and finding out at the end of the road what could have been, or if breath is still in our lungs is there a lesson learned from this. Do we even acknowledge the thanks and appreciation for the blessing we’ve been given by still having life. If I didn’t believe where would I be.
