Try to develop a more insoucient attitude to your personal safety(difficult if you have children). I don't have a death wish but i have a very carefree attitude regarding my own mortality. Being dead surely isn't that bad, i've never heard anyone complain about it. A mid air collision is better than a protracted lung cancer. If you can cultivate this attitude coupled with the knowledge that flying is safe, you will be fine.
