After all is said and done, what matters is that how our time here on earth fulfilled God's purpose or not and this is no different for your children.
Their experiences, resources, relationships, time, gifts, talents, net worth, network, competencies...EVERYTHING was designed to give God glory. That is purpose.
I pray that your children will live with this consciousness! That is true fulfillment. The "made" living according to the "maker's" intent and purpose!
