For those of us that can't fool ourselves into believing in eternal life, I think staying active is the best way to "get over" your mortality.
Columbus supposedly asked his crew what they would be doing if they weren't out on the ocean, risking their lives. Would they really be happy, or would they just be either troubled or bored? At least by risking their lives and constantly sailing into the unknown, they weren't bored, and they valued their life and things many take for granted.
You're more likely to get hung up on your mortality when you're bored.
