If you are wondering whether remembering your history is worth the trouble, know that there is biblical precedent for doing so. God told the Israelites to remember their past, both good and bad and it's the same for believers today if we are going to walk closely with the Lord.
Oft-times God will require us to remember particular events/occasions and seasons and commemorate them. Therein you will find incredible lessons, God's dealings with man and His faithfulness.
