Organizations, relationships, physical objects-all the things that you build may be destroyed during your lifetime. You could lose them overnight. If they survive your own passing, they may not survive for long, because the world will continue to change. Buildings will be torn down, new inventions will replace the old, new ideas will be adopted, new organizations will arise, new relationships will be formed.
But it is worth building anyway. It is worth it because the act of buidling brings joy and satisfaction. And even when the things you build are destroyed, that doesn't change what you have accomplished. What you accomplished was real. You will always be able to look back on it with pride and pleasure. What you accomplished can be a source of meaning forever.
