We must never lose sight of the fact that we are not lone travellers on this earth. There are always others who are trying to race ahead of us in this world of competition. The resulting situation can be approached in two entirely different ways. One is to collide with anything which obstructs our path. The other is to circumvent obstacles and then to go on our way. Clearly, the first is self-destructive, while the second, in avoiding confrontations, is much more likely to prove advantageous. A ship which sails straight at a rock or an iceberg is doomed to disaster. It is the ship which veers temporarily off its course to avoid the reefs which will eventually sail safely into harbour.
