easy way out

is there really an easy way out? A friend has been complaining abt his workplace for weeks, abt tough boss, bad colleagues, challenging assignment, etc... Should he quit or stay? I would try hard to stay, as the saying goes "When the going gets tough, the tough get going". To me there is no such thing as an easy way out. If he quits, what is the guarantee that he will not face the similar situation in the new company? quit again? be your own boss?

This is life. And life is not always a bed of roses - even roses have thorns!!
