I had to stop hoping so much that a ship ... would rescue me. I should not count on outside help. Survival had to start with me. In my experience, a castaway's worst mistake is to hope too much and do too little. Survival starts by paying attention to what is close at hand and immediate. To look out with idle hope is tantamount to dreaming one's life away.
