I'm all for self-improvement, goals, and progression, but there is definitely a time to look back and acknowledge all that you've done. The many acts of service will not be forgotten by God. You can't do everything, but you have done a lot of good through the years. Yes, we rely entirely on the grace of Christ for salvation, but we can show our appreciation and love for Him through our determination to bless as many lives as we can.

Just as "God saw every thing that he had made, and, behold, it was very good" you can look back and find comfort in the hours and hours and hours of good that you have done. You should absolutely recognize that most of your mortal life has been spent helping family, friends, neighbors, and strangers. This earth is a better place because of your efforts. You are better than good, you are literally an angel on earth.
